Problems solved by technology

[0004] (1) At present, the cost of using the oil film cleaning machine is relatively high, which is a great economic burden for small and medium-sized shearing enterprises or enterprises with few such orders
[0005] (2) The existing technology only uses cotton cloth to absorb the oil on the surface of the steel plate, without any treatment on the cotton cloth, resulting in a short service life of the cotton cloth and frequent replacement, resulting in a waste of resources

preparation example Construction

[0064] The embodiment of the present invention provides a preparation method of a special energy-saving agent for oil pollution prevention. The preparation method of the special energy-saving agent for oil pollution prevention comprises the following steps:

[0065] S201, weighing required parts by weight of n-decyl alcohol, nano-scale ceramic powder, nano-scale ceramic powder dispersant, oil-soluble chitosan derivative solution, auxiliary additives, and antioxidant with a balance.

[0066] S202, adding nano-ceramic micropowder and nano-ceramic dispersant into a ball mill, grinding at room temperature for 3 hours, then adding n-decyl alcohol and oil-soluble chitosan derivative solution to the ground material, and mixing evenly.

[0067] S203, put the mixture obtained in S202 into a mixing tank, add auxiliary additives and antioxidants, and stir for 2 hours to obtain a special energy-saving agent for oil pollution prevention.

Embodiment

[0070] In the embodiment of the present invention, during slitting and crimping, the pressure sensor installed on the tension plate of the slitting machine senses the contact pressure between the cotton cloth and the upper and lower surfaces of the steel plate, and the collected pressure information is transmitted to the slitting machine control system, and the slitting machine controls The system compares the built-in pressure setting value with the data transmitted by the pressure sensor, and sends the compared control command to the steel belt operation control device; when the data transmitted by the pressure sensor is greater than the set value, it controls the cotton cloth on the steel belt and the surface of the steel plate. The degree of fit decreases; the data transmitted by the pressure sensor is less than the set value, then the degree of fit between the cotton cloth on the steel belt and the surface of the steel plate is controlled to increase, and the oil and oil on...

Abstract

The invention belongs to the technical field of slitting processing of steel coils or steel plates, and discloses a method for reducing oil pollution in slitting processing. According to the width of slitting raw materials, two wool felts larger than the width of raw materials are selected; A piece of cotton cloth, the cotton cloth needs to cover the entire surface of the felt, and is bound and fixed with strong tape; when the slitting steel belt passes through the tension plate of the slitting machine, a piece of wool felt wrapped with cotton cloth is placed on the top and bottom of the steel belt; the slitting process is curled, passed The contact between the cotton cloth and the upper and lower surfaces of the steel plate absorbs oil and oil stains on the surface of the steel plate; according to the oil and oil stains on the steel plate surface, stop the machine every time one ton is processed to check the surface smoothness of the finished product and the oil absorption degree of the cotton cloth. The cotton cloth used in the invention can absorb the oil and oil stain on the surface of the steel plate, and changing the cotton cloth frequently can reduce the oil stain on the surface by more than 50%; the cotton cloth rubs against the steel plate under the pressure of the tension plate, and can disperse the oil stain blocks on the steel plate to improve the aesthetics of the steel plate.

Description

technical field [0001] The invention belongs to the technical field of slitting processing of steel coils or steel plates, and in particular relates to a method for reducing oil pollution in slitting processing. Background technique [0002] At present, the closest prior art: steel coil surfaces are generally oiled and divided into several categories: oil-free, lightly coated, medium coated, and heavily oiled. When processing hot-dip galvanized materials, the surface of the steel plate is squeezed and rubbed by the pinch roller, the pressure plate, and the wool felt of the tension plate, causing the zinc powder of the zinc layer to fall off, and the zinc powder and the oil on the surface of the steel coil combine to form black or gray "oil stains". When some small and medium-sized steel mills roll steel, cold-rolled materials will also have similar oil pollution problems due to process problems. Heavy oil and oil pollution will affect the surface quality of steel coils and ...
