A metal-aluminum bonded silicon-free low-carbon aluminum-zirconium-carbon slide plate for casting high manganese steel and its production method

Abstract

The invention discloses a metallic aluminium and non-silicone low-carbonalumina-zirconia-carbon slide plate for pouring high manganese steel. The metallic aluminium and non-silicone low-carbon alumina-zirconia-carbon slide plate for pouring the high manganese steel is prepared from a main ingredient and an addition agent, wherein the main ingredient is prepared from the following raw materials in percentage by weight: 39 to 50 percent of dense electro-fused alumina, 6 to 10 percent of alpha-aluminum oxide micropowder, 25 to 35 percent of fused alumina zirconia, 4 to 8 percent of silicon carbide, 4 to 6 percent of metal aluminum powder, 2 to 6 percent of zirconium oxide powder, 1 to 3 percent of carbon black, and 0.5 to 1 percent of boron carbide; the addition agent is phenolic resin; the weight of the addition agent is 4 to 6 percent of the total weight of the main ingredient. A production method comprises the steps of weighing the raw materials according to the weight, and uniformly mixing to obtain a clay; extrusion forming, drying for 8 to 10h at the temperature ranging from 190 to 210 DEG C, hooping, grinding, and drying to obtain the slide plate. The product provided by the invention has no need to be subjected to sintering and oil immersing, is simplified in process and short in production cycle, cannot cause pollution to the environment, has excellent oxidation resistance and corrosion resistance, can meet the use requirement on continuous sliding for 3 to 4 times through a research and development experiment, and has a remarkable comprehensive benefit.

Description

technical field [0001] The invention relates to an aluminum-zirconium-carbon slide plate, in particular to a metal-aluminum bonded silicon-free low-carbon aluminum-zirconium-carbon slide plate for casting high manganese steel and a production method thereof. Background technique [0002] With the deepening of the adjustment of the variety structure of the iron and steel industry, the output of special steel has increased rapidly. Strong, causing carbon oxidation in the skateboard, resulting in loose structure; at the same time, high MnO content is more corrosive to the skateboard. The second is that the pouring temperature is relatively high, which further intensifies oxidation, erosion and erosion. Currently casting high manganese steel using Al 2 o 3 -C, Al 2 o 3 -ZrO 2 -C skateboard, wherein the C content is generally 6-10%. Due to the high C content, the pores increase after oxidation and the structure is loose. MnO and SiO in skateboard 2 、Al 2 o 3 The reacti...

Problems solved by technology

Second, the pouring temperature is relatively high, which further intensifies oxidation, erosion and erosion

Therefore, when casting high manganese steel, the sliding plate often has phenomena such as corrosion resistance, hole expansion, and roughness, which cannot meet the requirements of continuous sliding use. It is necessary to develop a new material for high manganese steel sliding plate
