< r: >: .>Mining I-beam, central welding of the door frame There is an I-beam, which solves the problem of a seam at the central joint when assembling the left and right door frames of the semi-circular arch type. At the same time, since each I-beam is of the same model, the connection between them is welded, and the processing technology is simple. The flatness of the surface on the door frame that joins the door panel is easy to ensure.

< r: >: .>The mine explosion-proof door is used at the wellhead where the fan is located, in order to prevent the mine from exploding< r>< > The explosion-proof door should be opened in time to facilitate the timely escape of explosive gas. After the gas overflows, the door body can be automatically closed. According to the shape of the wellhead, you can choose whether to use an inclined shaft explosion-proof door or a vertical shaft explosion-proof door.
