Embodiment 1

[0015] The following combination figure 1 , 2 Describe the specific structure of the composite guide roller provided by the present invention.

[0016] The roller base 10 of the guide roller is made of ordinary carbon steel, and the roller surface of the roller base 10 is coated with a heat-resistant and wear-resistant hard surface layer 20. The roller surface of the roller base 10 and the surface layer 20 There is a metallurgical bonding layer 30 in between.

[0017] exist figure 1 Among them, the medium carbon steel is used to process the roller base 10 first, and its specific structure is a conventional mechanical part, including machining a bearing hole 11 in the middle of the roll base 10, which is very convenient to process, and then the hard surface layer 20 is processed. .

Embodiment 2

[0019] The processing method of composite guide roller comprises the following steps:

[0020] a. Select carbon steel to process the roller base of the guide roller and clean the surface; and configure alloy powder;

[0021] b. Slurry the above-mentioned qualified alloy powder and apply it on the surface of the roller base of the guide roller;

[0022] c. Place the guide roller coated with alloy powder in an oven at a temperature of 80-100°C for 1-2 hours, and finish the shape after leaving the box;

[0023] d. Put the dried guide roller in the vacuum furnace, and the vacuum degree is controlled at 10 -5 ~10 -6 Mpa, heated at 1030-1050°C and kept for 5 minutes;

[0024] e. After the above-mentioned guide roller is kept warm, it is cooled to 180-200°C with the furnace and cooled to normal temperature.

[0025] Vacuum sintering is used to form a metallurgical bond between the steel base and the hard material layer, and the bond is very firm; sintering in a vacuum environment...

Abstract

The invention relates to a composite guide roller and the method for preparation, the roller base being prepared with plain carbon steel, the roller surface of the roller base being coated with a heat-stable and antiwear hard surfacing; the processing employing the vacuum sintering method, the base being prepared with simple carbon steel and the surface treated with hard material, which can save the cost of material and is convenient for mechanical manufacture, and it imposes the high hardness, the perfect abradability, and corrosion prevention onto the surface of the guide roller, besides keeping the original intensity and drawability of the base material.

Description

technical field [0001] The invention relates to an equipment device and processing method for steel rolling, specifically guide and guard rollers for guiding and assisting rolling blanks or finished products to pass through quickly and the processing method thereof. Background technique [0002] When rolling steel, the red steel touches the roller surface of the guide roller, which requires the roller surface of the guide roller to be heat-resistant and wear-resistant. If the guide roller is made of a high-quality material with heat resistance and wear resistance as a whole, the cost will inevitably be high, and the processing difficulty of the bearing hole will increase significantly. Therefore, there is no guide roller with satisfactory performance, low cost and convenient processing in the prior art for actual production. Contents of the invention [0003] The primary purpose of the present invention is to provide a composite guide roller with low cost and convenient p...
