Problems solved by technology

The powder metallurgy method is relatively simple to operate, but the disadvantage is that the matrix and the second phase material are not mixed uniformly, and the composite material is prone to cracks due to the volume shrinkage of the matrix during the sintering process.

Abstract

The invention discloses a preparing method of ceramic-metallic composite material, which comprises the following steps: 1) allocating basal body alloy material; choosing 2Cr33Ni48WC10MoFe8 nickel base metal as basal body alloy; 2) preparing composite ceramic phase particle; choosing Al2O3 particle coating with Ti powder as composite ceramic phase particle; 3) mixing the basal body alloy material and composite ceramic phase particle with volume ratio at 1:0. 15-0. 45; pelleting; 4) press-forming; 5) vacuum-drying; 6) vacuum-clinkering; getting the product. This invention possesses lower ceramic-metallic composite material heat transfer capacity and predominance high temperature property, which is fit for new type material of rolled steel heater block.

Description

technical field [0001] The invention relates to a preparation method of a ceramic-metal composite material, in particular to a preparation method of a ceramic-metal composite material for a steel rolling heating furnace slide block. Background technique [0002] In steel rolling production, slabs are heated in furnaces before rolling. The slider supporting the heated slab is required to be able to withstand the thermal erosion of the furnace gas in the oxidation-sulfurization atmosphere at 1250-1400 °C, and to withstand the high-temperature sliding friction of the heavy slab. [0003] At present, the slider in the steel rolling heating furnace is made of cast 2Cr33Ni48W10Mo superalloy, but its thermal conductivity is high, and it is easy to form a "black belt" on the surface of the billet, which will lead to the uneven structure and product performance of the rolled steel plate, affecting The quality of medium and thick plate products is guaranteed. [0004] In order to so...
