Embodiment Construction
[0016] A method for manufacturing a wear-resistant jaw crusher liner according to the present invention comprises the following steps:
[0017] 1. Prepare the alloy block 17 for subsequent use, the alloy block 17 is rectangular, one end of the alloy block 17 is provided with an embedded tie rod 16, and the alloy block 17 is provided with an embedded rib 18;
[0018] ② Prepare the sand mold of the wear-resistant jaw crusher liner, and set up a number of sand cavities in the shape of concave and convex connected along the length direction in the sand cavity;
[0019] ③ Coat the inner surface of the sand cavity with alkaline magnesia powder coating, the coating thickness is 0.3-0.5 mm;
[0020] 4. Place the alloy block 17 at the bottom plane of the groove of the sand mold cavity described in step 2. The alloy block 17 is arranged along the length direction of the bottom plane of the groove, and the distance between the edges of the gold blocks 17 adjacent to each two length direc...

Abstract
The invention discloses a manufacturing method for an abrasion-resistant jaw crusher liner plate and provides a manufacturing method for an abrasion-resistant jaw crusher liner plate. High manganese steel is adopted as a base of a liner plate casting, and the purpose of prolonging the service life of the liner plate is achieved through the preparation method. The method has the advantages that a furnace cover structure is provided for protecting gas from diffusing easily, heat losses can be reduced, the smelting efficiency is improved, the furnace hearth insulation effect can be achieved, thus, a furnace lining is cooled slowly, the possibility of cracks of the furnace lining is lowered, and the service life of the furnace lining is prolonged. The furnace cover structure provided by the invention has the advantages of being easy to open and close, capable of distributing argon evenly and easily and the like.
Description
technical field [0001] The invention relates to a crusher, in particular to a manufacturing method of a wear-resistant jaw crusher liner. Background technique [0002] The jaw crusher is mainly used in the mining industry. The whole machine is large in size and high in cost, and its working liner is a vulnerable part. Such a liner has a short service life and needs to be replaced frequently, and the replacement operation is complicated and takes a long time, which affects production efficiency and leads to increased production costs. For this reason, the material of the liner is constantly replaced in the art to increase its wear resistance, so as to improve the service life of the liner. However, various wear-resistant materials of the liner have been found to be unable to greatly improve the service life of the liner. The high manganese steel liner widely used at present is a liner with better effect, but it still has the disadvantages of loose shrinkage cavity of the li...
