Tire protection chain, is a link and connection between the link on both sides of the body of the chain components, connecting link in the side chain and the connection on both ends link chain docking component, on both ends of a link on both sides with a rope card fastening rope, subject chain component is open type, its fixed installation of opening reinforcement pin. In the process of using, maintenance chain good abrasion resistance, fatigue resistance is strong, according to the conditions of use life of 3000-8000 hours. So sometimes you will ask: how to make the tire chains. Because it is tear open outfit is convenient, save time and effort, the products are complete in specifications, can match with imported loader, tyre protection chain, using high-tech wear-resisting material, the new structure is compact, stable performance, service life is short, the tire is expensive, the cost is high, will this product tightly wrapped in loader tires, can effectively protect the loader tires, not by the sharp rocks cut prick, prolong the service life of the tyre, use a tyre protection chain, can save the cost of more than ten tires, can improve the work efficiency and safety of loader is an essential for mining operation. Below to introduce a forklift protection chain is how to make the tire chains.
A forklift truck tyre protection chain link steel, its components and wt % to: C: 0.6 ~ 0.8% and Si: 1.0 ~ 1.2%, Mn: 0.3 ~ 0.7%, P ≦ 0.015%, S ≦ 0.01% and Cr: 0.3 ~ 0.5%, Ni0.9 ~ 1.2%, Co: 0.01 ~ 0.02%, V: 0.16 ~ 0.2% and Mo: 0.4 ~ 0.6%, Als: 0.03 ~ 0.05%, W: 0.03 ~ 0.05%, N: 0.008 ~ 0.01%; Production process: hot metal desulphurization; The converter smelting; Argon blowing and feeding aluminium wire; In well bottom note type used on the sand of casting; Demoulding after natural cooling to room temperature; Heat of steel ingot and forging into shape. Prepared by the invention of forklift protection chain link the vickers hardness of not less than 650, can adapt to work under high temperature above 300 ℃, 5000 hours, and use of converter can produce, make the efficiency can be improved, relative to the electric furnace production, can significantly reduce the cost. Actually for other tire protection chain is how to make the tire chains, with the forklift protection chain of production has the same effect.
