In the production process of the steel wire rope, it is extremely important to control the color of the colored oil strand, the thickness of the oil film, and reduce the difference in the color of the oil strand produced in different batches. Once the color of the oil strand deviates, it will involve the problem of infringement of the supplier's product, and certain legal responsibility and economic compensation will be borne. Therefore, the consistency of the color of the oil strand of the steel wire rope in different batches is crucial. The existing colored oil strand has poor adhesion of the colored oil in the production process, and some thickening agents are added in the oil to improve the adhesion of the oil, which causes smoke and peculiar smell during oil melting, pollutes the environment, and affects the physical and mental health of employees. Secondly, due to the unquantifiable process parameters of the colored oil strand, the colors of the colored oil strands in different batches are inconsistent, and the cost of rework is large.

BRIEF DESCRIPTION OF DRAWINGS

[0025] Figure 1 is the flow chart of the color oil strand production process of the present application. DETAILED DESCRIPTION

[0026] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0027] The color oil strand production process of the present application, the process is as shown in Figure 1 , and is implemented according to the following steps:

[0028] Step 1, first oil coating of the strand rope, add base oil to the container, stir and heat to 90-105 DEG C to melt the oil, normally strand the rope, and give the first oil coating to the strand rope at the strand closing opening with the melted base oil, the first oil coating temperature is 95-110 DEG C, and then wipe the surface of the strand rope with medical rubber, coil or rubber strip at the position of the mold base, until the oil film on the surface of the strand rope is uniform, to obtain the first oil coating strand rope;

[0029] Among them, the base oil selects light-colored oil with a drop point ≥85 DEG C and a viscosity / cp value ≥2000 at 100 DEG C oil temperature, which is convenient for re-coating, and the dark strand is not easy to color, and the light-colored oil strand is used to lubricate the strand rope, to ensure that the oil of different layers of steel wire in the strand rope is uniform, and the lubrication effect during the use of the strand rope is not affected.

[0030] The base oil has a low temperature ≥-35 DEG C, and the base oil must be able to dissolve each other with the oil color paste;

[0031] The performance parameters of the base oil are very important, first of all, the color of the oil should be light, secondly, the drop point and adhesion of the oil, the higher the drop point of the oil, the better the adhesion performance, and the stronger the adhesion of the oil. The oil can be used at different operating environment temperatures without cracking; secondly, the base oil must be able to dissolve each other with the oil color paste.

[0032] Check the compatibility of the base oil and the oil-based color paste. You can prepare about 50g of the base oil, put it in a glass, heat it in the laboratory until it dissolves, add about 2-3g of the oil-based color paste, stir it evenly with a glass rod, and observe whether the two dissolve in each other after it cools naturally.

[0033] The container can be a medium-oil pan.

[0034] Step 2, Making Colored Grease:

[0035] 2.1 Preparation of raw and auxiliary materials,

[0036] Weigh out the base oils, oil-based color pastes, and pigment additives by mass percentage;

[0037] The base grease is the same type as the base grease in step 1.

[0038] The mass ratio of base oil to oil-based color paste is 15-25:1; the mass ratio of base oil to pigment additive is 1:0.003-0.006. If the additive ratio is not appropriate, the color of the oil may change and become dark.

[0039] Oil-based color pastes are organic oil-based color pastes;

[0040] The color of the oil-based colorant is a key parameter in selecting colored oil-based strands. The appropriate color of oil-based colorant is chosen based on the requirements. This can be done using a single color oil-based colorant or by mixing two colors. For example, a grass-green oil-based strand can be mixed from green and yellow oil-based colorants, while a rose-red oil-based strand can be directly generated using a single rose-red oil-based colorant. Secondly, the oil-based colorant must be organic to ensure the safety of the grease on the steel wire rope surface and to prevent harm to the human body.

[0041] The pigment additive is a water-soluble additive. It is prepared with boiling water to reduce the water content of the oil. The pigment additive's function is to improve the color brightness and adhesion of the oil, thereby reducing the production cost of colored oils.

[0042] 2.2 Add the pigment additive weighed in step 2.1 to boiling water at a mass ratio of 1:6-10. Stir well to obtain diluted pigment additive. Color matching: Add the base oil weighed in step 2.1 to an empty container in small amounts several times. Stir and heat to 90℃~105℃ until completely melted. Then add the oily color paste weighed in step 2.1 to the container and stir well. After the color of the mixed oil in the container reaches the expected level, add the diluted pigment additive to the container and stir well to obtain the colored oil after color matching.

[0043] When adding oil-based color paste, you can first select the amount of oil-based color paste according to 25:1, observe whether the color of the oil achieves the expected effect, and add more slowly if it is insufficient.

[0044] Step 3, the first oiling strand of step 1 is placed on the pipe doubling machine reel with damping device, the oil pan with color grease in step 2 is placed between the rear straightener and the take-up machine of the doubling machine. The first oiling strand is wound around the traction wheel for 5-6 turns and is introduced to the color oil pan through the rear straightener to be oiled for the second time. The second oiling temperature is 90-105 DEG C. The strand surface is scraped and then is introduced to the take-up machine through the oil pan guide wheel. The color oil strand is obtained by scraping.

[0045] The color grease obtained in step 2 is used to oil the first oiling strand of step 1 for the second time. The strand surface is wound with 1.8-2.0 mm iron wire for 2-3 turns through the oil pan guide wheel. The surface grease is scraped to make the strand surface grease uniform.

[0046] The thickness and uniformity of the strand surface oil film are observed during scraping to determine the tightness and number of turns of the iron wire wound on the strand. Too many turns of the iron wire wound on the strand or too tight winding of the iron wire on the strand will result in too thin strand surface oil film. Too few turns of the iron wire wound on the strand will not scrape the oil and the strand surface grease will be too much and the oil film will not be uniform.

[0047] The vehicle speed is controlled according to the strand laying quality. The take-up machine speed is 200-400 r / min to ensure that the color oil strand is coated with uniform oil film and the take-up quality is good.

[0048] The color oil strand produced by the color oil strand production process can be twisted with other strands coated with normal grease to produce steel wire rope according to requirements and is suitable for color oil strand production of steel wire rope.

[0049] The color oil strand production process has good base grease adhesion, high drop point and light color. The oily color paste must be well dissolved in the base grease. The color additive is selected to improve the color brightness and grease adhesion. The oily color paste amount can be effectively reduced and the cost is reduced. The color oil strand produced has stable quality, low cost and green environmental protection.

[0050] Example 1

[0051] The grass green color oil strand production process is implemented according to the following steps.

[0052] Step 1. First oiling,

[0053] Base oil: KL-GS655, light color grease with drop point greater than 85 DEG C;

[0054] The base oil KL-GS655 is added to the oil pot, heated to 98℃, and the oil is melted. The strands that need to be coated with colored grease are normally twisted and sprayed. The first spraying temperature is 103℃. The spraying is carried out at the closing port, and the surface grease of the strands is scraped clean with rubber after twisting to make the surface oil film uniform and without excess grease, and the first spraying strands are obtained.

[0055] Step 2. Preparation of colored grease,

[0056] 2.1. Preparation of raw and auxiliary materials,

[0057] Base oil: KL-GS655, light color grease with a drop point greater than 85℃;

[0058] Oily color paste: Select green and yellow organic color paste, grease color matching ratio: base grease to oily color paste mass ratio is 20:1, green organic oily color paste to yellow organic oily color paste mass ratio is 3:2.

[0059] The amount of food color additive is selected to improve the color brightness and adhesion of the grease, and the mass ratio of the base grease to the color additive is 1:0.003.

[0060] 2.2. Melting and color matching,

[0061] The KL-GS655 base grease in step 2.1 is added to the oil pot several times in small amounts, the oil pot is heated to 98℃ using medium oil, and the grease can be stirred appropriately to improve the uniformity of the grease temperature. First, slowly pour the prepared green organic oily color paste into the oil pot with melted KL-GS655, stir evenly, and observe the color of the mixed grease. Then slowly add yellow organic oily color paste until the color of the grease is close to the desired color. Add the amount of food color additive to boiling water, the mass ratio of color additive to boiling water is 1:8, stir evenly to get the diluted color additive, add the diluted color additive to the oil pot, stir evenly to get the grass green grease.

[0062] Step 3. Second spraying,

[0063] The first oiling strand is placed on the pay-off rack with damping device, and the secondary oiling process is implemented by using the tubbing stranding machine. The color oil pot is placed between the stranding machine and the take-up machine, and the strand passes through the color oil pot guide wheel to be oiled for the second time. The second oiling temperature is 98 DEG C. After the strand coated with color oil passes through the oil pot, an iron wire with a diameter of about 1.9 mm is wound on the surface of the strand for 3 turns, and then the iron wire is loosened appropriately. The other end of the iron wire is fixed on the oiling pay-off guide wheel, and the surface oil is scraped to make the surface oil of the strand uniform. The tightness of the iron wire can be adjusted to control the thickness of the oil film. In order to ensure the quality of the strand pay-off, the strand coated with grass green oil must pass through the post-deformation device and be slightly pressed, and then pass through the traction wheel to the take-up machine to be taken up, so that the grass green oil strand is obtained.

[0064] The rotation speed of the take-up machine is 300 r / min.

[0065] The grass green oil strand can be used to produce color oil strand steel wire rope with anti-fake mark. The grass green oil strand produced and other normal oiling oil strands are combined according to the required number of color oil strands to produce the color oil strand steel wire rope.

[0066] The color oil strand production process has the advantages of bright color, low production cost, high efficiency, no pollution to the production environment, etc. The oil used is light yellow transparent oil KL-GS655.

[0067] Most of the prior art uses imported Japanese CH-1 oil. The traditional color oil strand production process uses Japanese CH-1 oil as the base oil, the drop point is 70-80 DEG C, CH-1 oil is not soluble with oily color paste, when the oil pot temperature is low, the oil will float on the surface of the oil pot, the color paste will sink to the bottom of the oil pot, and a large amount of color paste is needed to achieve the expected effect when adjusting the color. And the surface oil film of the strand produced by using CH-1 oil as the base oil is very thin, and the oily color strand cannot achieve the expected effect. In order to improve the adhesion of the color oil strand, a small amount of latex paint is added to the oil pot, and the oil needs to be stirred constantly when the oil is being produced, which will produce smoke from the oil pot and have an odor, affecting the working environment. The color oil strand produced has poor adhesion, and the oil is easy to fall off when not scraped during oiling. The surface of the strand is coated with oil, and the oil is thrown out during stranding, which pollutes the environment. When the pay-off tension is small during the secondary oiling, the strand pay-off is not uniform, and the strand is broken during stranding, which causes the steel wire rope to be short and unqualified.

[0068] The KL-GS655 oil of the embodiment 1 of the present application is 10000 yuan / ton lower than the prior art oil, the drop point is 85-95 DEG C, the drop point is high, the adhesion is good, can be dissolved with the selected oily color paste, compared with the imported CH-1 oil, the same color oil can be prepared by using the KL-GS655 oil, the amount of the oily color paste is 50% less than that in the traditional color oil production process, the surface oil film of the color oil is uniform, the color of the steel wire rope produced by different batches is consistent, and the color inconsistency of the color oil is reduced.

[0069] Product cost calculation:

[0070] The price of the oily color paste is 600 yuan / kg, if 100 kg of color oil is prepared, the imported CH-1 oil is used in the traditional process, the price of the imported CH-1 oil is 28 yuan / kg, the KL-GS655 oil is used in the embodiment 1 of the present application, the price of the KL-GS655 oil is 18 yuan / kg, 12 kg of the oily color paste is needed for 100 kg of the oil in the traditional process, and about 30% of the color oil is wasted due to poor adhesion of the oil.

[0071] The cost of the base oil and the oily color paste in the color oil production process in the embodiment 1 of the present application is calculated as follows:

[0072] The cost of 100 kg of the base oil plus the oily color paste is equal to the cost of the base oil plus the cost of the oily color paste,

[0073] The cost is equal to 100*18 (the price of the base oil) plus 5*600 yuan / kg (the price of the oily color paste), that is, 4800 yuan. 105 kg of the color oil can be produced, the oil content of the color oil is 2.5%, and 6 ropes are coated with only one strand, which accounts for 1 / 7 of the weight of the steel wire rope, so that 105 kg of the oil can produce the steel wire rope with a weight of 105 / 0.025*7=29.4 tons. The cost of one ton of the product is 4800 / 29.4=163 yuan.

[0074] The cost of the base oil and the oily color paste in the traditional color oil production process is calculated as follows:

[0075] The cost is equal to 100*28 plus 12*600 (the price of the oily color paste), that is, 10000 yuan.

[0076] 112 kg of the color oil can be produced, 30% of the oil is wasted when the color oil is coated, the oil content of the color oil is 2.5%, and the weight of the oil that can produce the steel wire rope with a weight of 112*(1-30%) / 0.025*7=21.9 tons is 112 kg, and the cost of the color oil is 10000 / 21.9=456 yuan / ton.

[0077] The cost reduction of the color oil of the embodiment 1 of the present application is 456-163=293 yuan / ton, and the production cost is reduced by 64% compared with the traditional process.
