A method and equipment for preparing fire-resistant and anti-corrosion C-shaped steel

Abstract

The invention discloses a method and equipment for preparing fire-resistant and anti-corrosive C type steel, and belongs to the technical field of anti-corrosive building material. The equipment comprises a bonding hole punching machine, a forming machine and an extrusion cladding machine arranged in sequence from front to back; the equipment is characterized in that an extrusion die is mounted inside a package molding machine, a C type steel inlet is arranged on the front end of the extrusion die, a C type steel outlet is arranged on the rear end of the extrusion die, the C type steel outlet is larger than the C type steel inlet, a cladding chamber connecting the C type steel inlet and the C type steel outlet is arranged inside the extrusion die, a flow pass connecting the cladding chamber is arranged in the side wall of cladding chamber, the other end of the flow pass is communicated with a filling port, and the filling port is connected with a plasticizing extruder. When the C type steel is extruded and cladded, the cladded material in a melted state is extruded to the upper surface and the lower surface of the C type steel through the flow pass, then through being connected by the bonding hole, the complete set of equipment enables the cladding layer to form a whole with multiple connection points, which reinforces the robustness, thereby the lasting anti-corrosive ability of the C type steel is heightened.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion building materials, and in particular relates to a method and equipment for preparing fire-resistant and anti-corrosion C-shaped steel. Background technique [0002] Now, the workshops of many chemical factories use color steel houses. If the acidic or alkaline substances in the workshop volatilize into the air, some of them will adhere to the wall or the surface of the C-shaped steel, which will cause serious damage to them after a long time. Corrosion will endanger the load-bearing system of the color steel house over time and cause safety hazards. This puts forward higher requirements for the anti-corrosion of building materials in the workshop. Now, the anti-corrosion materials on the walls and houses have been well solved. However, the anti-corrosion effect of C-shaped steel has not been good. Generally, color-steel houses are loaded with ordinary C-shaped steel. The anti-corrosion mea...

AI Technical Summary

Problems solved by technology

When the current anti-corrosion C-shaped steel encounters the above-mentioned high temperature conditions, its cladding layer will melt and peel off, which will affect its anti-corrosion performance in subsequent use.
