W steel is a new type mine and tunnel roof, side wall material.
       The influence of pressure, after use, prone to deformation phenomenon, previously recycled under W type steel strip is mainly through the well organized artificial hammer repair, both time consuming, and labor. In order to effectively reduce the cost of repair, Shandong with the Swiss mining technology decision on recycling strip directly in the underground - 350 track repair station repairs. In order to ensure that W steel repair quality, development of the company made a new press mold, the deformation of W steel in the press by mold pressing for correction of deformation, so as to achieve the reuse requirements.
       W steel repair mold using the upper and lower mold structure, in order to ensure the strength of die, through the plane out of two and W steel strip bulges corresponding to the 50 mm thick steel plate groove bottom welding I-steel, fixed on a press working table approach consisting of lower mould, mold through the use of 20 mm steel plate welded H-shaped steel reinforcement, and in steel by with female wire splint and press the telescopic rod. Composed of the upper and lower body mold. Extremely effective conservation of the explosion-proof dehumidifiers mold cost.
       The company asked the shop to pay close attention to the w strip repair mold production and sales situation, actively carry out the efficient production, with the fastest speed, the best quality of products on the market.
