Silicon Carbide Plastic Refractory Definition
Silicon carbide plastic is made of high-alumina bauxite clinker, corundum, mullite and silicon carbide, SiC plastic refractory is made of different binders and admixtures. Silicon carbide refractory plastic has high-strength wear-resisting refractory material and has convenient construction. Silicon carbide refractory plastic have good plasticity and good wear resistance.
Silicon Carbide Plastic Refractory Features
1.Refractory SiC plastic has the advantages of convenient construction, good plasticity and good wear resistance.
2. Plastic silicon carbide is a kind of advanced refractory material, Silicon carbide refractory plastic has excellent wear resistance, super strong adhesion and high service temperature (1200 ° C), the construction process is simple, the construction period is short, and no oven is needed after the construction is completed. Known for refractory SiC plastic superior characteristics and practiced. Silicon carbide refractory plastic service life is significantly higher than other wear-resistant refractories.

Silicon Carbide Plastic Refractory Application
1. Silicon carbide refractory plastic suitable for all kinds of thermal furnaces
2. Plastic refractory silicon carbide mainly suitable for large heating furnace lining.
3. Plastic refractory silicon carbide mainly suitable for intermediate frequency furnace repairing materials.
4. Silicon carbide refractory plastic electric furnace repairing materials, ore furnace iron mouth.
Silicon Carbide Plastic Refractory advantage
1.Silicon carbide refractory plastic has a certain plasticity to facilitate construction.
2.Silicon carbide refractory plastic has a certain shelf life to ensure that the molding performance is unchanged during the specified storage period.
3.After curing at room temperature, plastic refractory silicon carbide has a certain strength to facilitate the removal of the frame or handling after construction.
4.SiC plastic refractorines has a certain high temperature volume stability to prevent damage to the lining structure caused by excessive deformation.
5.SiC plastic refractorines has a certain thermal shock stability and resistance to spalling.
Silicon Carbide Refractory Plastic Construction Method
1.The refractory plastic silicon carbide is constructed by applying the tamping and compacting method. Before the construction, the rigid anchoring nail tips should be fixed at the required parts. The anchoring nail tips are about 150-250mm. The refractory plastic can be laid at the required part and evenly applied to the required part. The thickness of the blank can be determined according to the design requirements of different furnace types.
2.Silicon carbide plastic refractory has superior bonding performance, refractory plastic can be applied to any irregular wear parts, the wear degree is greatly reduced. SiC plastic refractorines does not need to use steel template or mold, refractory plastic can be ignited immediately after construction, without special maintenance. Thereby shortening the construction period and saving costs.
Silicon Carbide Refractory Plastic Trimming and Curing
1.After the silicon carbide plastic is beaten and the template is removed, the trimming should be carried out on the surface of the material in time. The refractory SiC plastic of trimming effect is to remove the dense layer of the material to form surface pores, SiC refractory plastic is beneficial to the gas during the baking of the lining. Discharge to avoid cracks. Before the dressing, the refractory plastic around the end face of the anchor brick or the hanging brick is gently tapped with a wooden mallet to make the bite tight. The trimming work is based on the anchor brick end face, the excess part is removed. The uncut surface should be roughened.
2.Before the trimmed silicon carbide plastic furnace wall is not hardened, a vent hole with a diameter of 4~6mm should be opened on the heated surface, the spacing should be 150~230mm. The position should be between the two ancho refractory bricks, the depth is about solid. The thickness of the refractory brick is 1/2~2/3.
3.The expansion line of the refractory plastic lining heating surface should be cut according to the position of the juice setting, the width should be 5mm, and the depth should be 50~80mm.
5. After the trimming of the Sic refractory plastic lining, if refractory plastic cannot be ovened in time, plastic refractory should be covered with plastic sheeting. Silicon carbide plastic refractory is normal to form fine water droplets on the inner surface of the plastic cloth during the curing period.
Silicon Carbide Refractory Plastic Crack Repair
1.Before the oven, the plastic liner lining crack width should be more than the following dimensions: 3mm for the burner and each hole, 5mm for the temperature or important part; 12mm for other parts. The crack should be dug into a small wedge-shaped opening in the inside and outside, sprinkled with misty water, and carefully filled with SIC refractory plastic.
2.When the crack width is in the following dimensions, it is not necessary to make a fill: the burner, each hole is 1~3mm; the high temperature or important part is 1~5mm; the other parts are 3~12mm. At this point, the method of filling the seam can be adopted, that is, the spray water is wetted at the crack, tapped with a raft to close the crack, or filled with refractory mud, refractory plastic, refractory fiber.
