Hard alloy for soaking plate and soaking plate made of hard alloy

Abstract

The invention discloses a hard alloy for a soaking plate. The hard alloy is characterized in that the hard alloy is prepared by means of the method that Cr3C2 and Cu are added into a super coarse grain WC-14Ni alloy, wherein all raw materials are weighed according to the mode that the raw materials comprise, by weight, 1.0-2.8% of Cr3C2, 0.5-3.5% of Cu and the balance super coarse grain WC-14Ni alloy. By adopting super coarse grain WC and adjusting the component ratio of Cr3C2 and Cu, a compact oxidation film protection layer is formed on the alloy surface of the soaking plate under the high-temperature work condition, thus the soaking plate has extremely good high-temperature-oxidation-resisting performance, and the heat conductivity and high-temperature hardness of the soaking plate canbe improved; and according to the hard alloy, preparation is easy, the performance of the soaking plate can be effectively improved, the gap of the field in China is filled up, and the current situation that the soaking plate of China relies on a foreign product is overcome, and huge economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of cemented carbide, and more specifically, to a cemented carbide for a soaker plate and a soaker plate thereof. Background technique [0002] In recent years, with the continuous expansion of the application field of cemented carbide, the material of cemented carbide has developed in two directions: ultra-coarse and ultra-fine. Ultra-coarse cemented carbide has been widely used in the fields of mining rock drilling tools, rolls and stamping dies . [0003] Compared with the 2D and 2.5D glass used in smartphones before, 3D curved glass adds a hot bending process to the molding of 3D curved glass. The stability of the hot bending equipment for 3D curved glass molding directly affects the product performance of 3D glass. When the hot bending machine presses 3D curved glass, it needs to go through the process of glass preheating, constant temperature pressing and cooling. In this process, the glass is heated and deform...

AI Technical Summary

Problems solved by technology

[0006] Vapor chambers are mainly used in thermoforming of curved glass, including mobile phone panel glass, lens glass, etc. The 3D glass hot bending machine was originally designed to use stainless steel plates as heat conduction and pressing support materials, and press special graphite through the upper and lower stainless steel plates The mold completes the curved surface forming of the flat glass in the graphite mold, but the stainless steel plate has a large amount of deformation under high temperature and uneven heat conduction, which makes it difficult to meet the process requirements of curved glass pressing. After adjusting the design scheme of the hot bending machine, through the stainless steel plate and graphite A vapor chamber is added between the molds to act as a uniform heat conduction and pressing support. At present, the materials of the vapor chamber include metal materials and non-metal materials. In terms of usage, they basically have thermal conductivity, high temperature oxidation resistance, high temperature The four properties of hardness and high temperature strength cannot be satisfied at the same time. Based on the four properties necessary for perfecting the vapor chamber, the vapor chambers in my country are all imported from foreign products, and it is difficult for domestically produced vapor chambers to meet the use requirements.
