[0002] At present, domestic wear-resistant strips / plates mostly adopt the manufacturing process of high-chromium cast iron precision casting and high-pressure welding with alloy steel plates. Although this product can be welded and wear-resistant, its impact strength is not high and it is not resistant to high temperature, so it can only be used at room temperature. / cutting, the cutting method is limited in use, only plasma, water cutting, diamond sawing and other cold processing methods can be used for cutting, and the use environment is limited. In case of high temperature welding, the joint part is easy to fall off, and the manufacturing process and production equipment are complicated. high production cost

Embodiment 1

[0012] One: Preparation of ceramic particles:

[0013] Choose ceramic powder with a diameter of 30-120μm, dry press the ceramic powder into blocks with an isostatic press, and then pre-fire. The pre-fire temperature is 1100-1200°C. Break the blocky ceramic powder, and screen the ceramic particles with a diameter of 1-3mm for later use;

[0014] After that, the spare ceramic particles with a diameter of 1-3mm are sintered at high temperature again. The sintering temperature is 1600-1650°C. After the sintering temperature reaches the heat preservation for two hours, it is naturally cooled to room temperature in the furnace, and the irregular shape is obtained after sintering. Ceramic particles with a particle diameter of 1-3mm. Two: Preparation of ceramic pellets:

[0015] Mix the final sintered ceramic particles with a diameter of 1-3 mm and iron powder with a particle diameter of 30-120 μm through a binder (the content of each component is selected according to the mechanica...

Embodiment 2

[0022] One: Preparation of ceramic particles and powder:

[0023] The selected particle diameter is 30-120μm Al 2 o 3 10-15 parts by weight of powder, ZrO2+Y 2 o 3 85-90 parts by weight of powder, mixed with the binder, dry-press the ceramic powder into blocks with an isostatic press, and then pre-fire, the pre-fire temperature is 1100-1200°C, and the block-shaped ceramic powder is obtained after the pre-fire temperature reaches Naturally cool in the furnace to normal temperature, then crush, screen the ceramic powder with particle diameter less than 1mm to form primary ceramic particles, and select the primary ceramic particles for high-temperature sintering again, the temperature for re-sintering is 1600-1650°C, pre-fired After reaching the temperature, heat the primary ceramic particles for two hours, then cool them naturally in the furnace to normal temperature, and obtain irregularly shaped ceramic particles with a diameter of less than 1mm after sintering to form seco...

Abstract

The invention relates to a ceramic high chromium composite reinforced cast steel wear-resistant strip / plate casting process. The technical solution adopted in the invention is to prefabricate the wear-resistant layer in advance, and then pour the wear-resistant layer and the wear-resistant strip body through the pouring operation Integrate the wear-resistant layer, or make the wear-resistant layer into a suspension agent, and use the specific gravity difference between the poured metal liquid and the suspension agent to realize the formation of the wear-resistant layer and the wear-resistant layer body during the casting process. The process of the invention is simple, and the metallurgical sintering process The method solves the problem of infiltration and compounding of the prefabricated core block and the casting body, so that the composite layer (that is, the wear-resistant layer) and the body of the wear-resistant strip are fused together without obvious boundaries.

technical field [0001] The invention relates to a ceramic high chromium composite reinforced cast steel wear-resistant bar / plate casting process. Background technique [0002] At present, domestic wear-resistant strips / plates mostly adopt the manufacturing process of high-chromium cast iron precision casting and high-pressure welding with alloy steel plates. Although this product can be welded and wear-resistant, its impact strength is not high and it is not resistant to high temperature, so it can only be used at room temperature. / cutting, the cutting method is limited in use, only plasma, water cutting, diamond sawing and other cold processing methods can be used for cutting, and the use environment is limited. In case of high temperature welding, the joint part is easy to fall off, and the manufacturing process and production equipment are complicated. Production costs are high. Contents of the invention [0003] In view of the shortcomings of the above-mentioned tech...
