Stemming extrusion forming device special for iron notch maintenance

Abstract

The invention discloses a stemming extrusion forming device special for iron notch maintenance. The stemming extrusion forming device comprises a main body, a feeding opening, a hydraulic cylinder, apiston, a supporting frame, a cutting device and a material outlet, wherein the feeding opening is formed in the upper end of the main body, a material cavity is formed in the main body, and the feeding opening communicates with the material cavity; the piston is arranged in the material cavity, and the hydraulic cylinder is arranged on the left side of the main body; the piston is fixedly connected with a telescopic arm of the hydraulic cylinder, and a material outlet is formed in the right side of the main body and communicates with the material cavity; and the cutting device is arranged atthe upper end of the material outlet and fixedly connected with the main body. The hydraulic cylinder and the piston are arranged, the piston is driven by the hydraulic cylinder to extrude stemming out of the cavity to achieve forming, and compared with the prior art, hydraulic press thrust is larger, and the forming effect is better; the piston is used for pushing the stemming, so that the stemming is not prone to blockage and clamping; and the cutting device is arranged to conveniently carry out cut-off shaping when the stemming is pushed out.

Description

【Technical field】 [0001] The invention relates to the technical field of foam mud processing equipment, in particular to the technical field of foam mud extrusion molding devices. 【Background technique】 [0002] Foam mud is a fire-resistant, corrosion-resistant, scour-resistant, and wear-resistant refractory material used in the metallurgical industry to block the iron hole of the ironmaking blast furnace and fill the gaps and cracks in the iron hole. The foam mud is made of aluminum silicate material , Sic, coke grains and other materials and binders, admixtures of refractory materials for plugging the iron hole. The foam mud has good viscoplasticity, easy sintering, erosion resistance, erosion resistance, good volume stability, and the depth of the iron hole is suitable. The use effect is good. In the production of foam mud, it needs to be extruded and then cut into bags. The traditional technology generally uses a screw conveying device to extrude the material. This metho...

[0002] Foam mud is a fire-resistant, corrosion-resistant, scour-resistant, and wear-resistant refractory material used in the metallurgical industry to block the iron hole of the ironmaking blast furnace and fill the gaps and cracks in the iron hole. The foam mud is made of aluminum silicate material , Sic, coke grains and other materials and binders, admixtures of refractory materials for plugging the iron hole. The foam mud has good viscoplasticity, easy sintering, erosion resistance, erosion resistance, good volume stability, and the depth of the iron hole is suitable. The use effect is good. In the production of foam mud, it needs to be extruded and then cut into bags. The traditional technology generally uses a screw conveying device to extrude the material. This method may spiral when facing some foam mud with high viscosity. The conveying device will be blocked by foam mud, unable to rotate, unable to extrude
