Introduction to 4 major techniques of chain heat treatment process

Chain special treatment process

 XNUMX. Heat treatment of chains and chain plates
　　  1. Tendency to thin permeable layer;
　　  2. Use the hardness gradient instead of the carbon concentration gradient measurement to obtain a gentle carbon concentration gradient, improve brittleness, and improve strength;
　　  3. Using controlled atmosphere quenching and carbonitriding;
　　  4. Carburizing with propane gas;
　　  5. Reduce the dependence on the converter, and replace the thick permeable layer products with a box-type multi-purpose furnace or a gas pit furnace;
　　  6. Use water agent instead of oil for quenching to reduce pollution.
XNUMX. Special technology
　　  Such as plating, stainless steel heat treatment, chromium infiltration, round cold riveting technology, thick plate punching and punching technology, bending of S-shaped steel roller chain special-shaped accessories, etc., can gradually be effectively solved.

Three, two running styles, active online oil on the effect of eliminating the moon tail effect, the role of grease.

Four, choose the right style of work
　　  1. Divide the plant area according to product categories;
　　  2. Arrange plant equipment according to the type of work;
　　  It should be said that when the scale of the enterprise has grown to thousands of different types of chain products, it is not clear that they will be produced in one factory area.
　　  3. When the external conditions are mature (quality, price, delivery time), chain parts can also be produced or outsourced.
