specific Embodiment approach 1

[0018] Specific embodiment one: the method for preparing the wear-resistant ceramic liner with the active brazing method in this embodiment is realized by the following method: one, by mass fraction, 60%~80% Ag powder, 18%~35% Cu Powder and 1%~5% TiH 2 Put the powder into a stainless steel tank after mixing, then add acetone to make the acetone 1-5cm higher than the mixed powder, then fill the stainless steel tank with inert gas, seal the stainless steel tank, and then ball mill for 25-30 hours, then mix the powder after ball milling Powder and binder are mixed to obtain active metal paste solder, wherein the mass ratio of ball to material is 20:1, the mass ratio of mixed powder to binder is 20:1, and the mass fraction of binder is from 0.8% to 1.2 % glycerol, 95% to 97% distilled water and 2% to 4% hydroxyethyl cellulose; 2. Clean the surface of the ceramic block and the low-alloy high-strength structural steel plate respectively, then dry it naturally, and then put the ceram...

specific Embodiment approach 2

[0022] Specific embodiment two: the difference between this embodiment and specific embodiment one is that in step one, 70% Ag powder, 27% Cu powder and 3% TiH 2 The powder is mixed and placed in a stainless steel tank. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0023] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the inert gas in step 1 is argon or helium. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a method for preparing an abrasion-resistant ceramic lining plate by using an active soldering method, which relates to a method for preparing an abrasion-resistant ceramic lining plate. The method solves the problems that the conventional adhesive abrasion-resistant ceramic rubber lining plate has low bonding strength, the ceramic is easy to drop, the rubber material is easy to age, and the conventional bolt connected abrasion-resistant ceramic lining plate is easy to tear and has short abrasion-resistant service life. The method comprises the following steps: firstly, preparing an active metal paste solder; secondly, treating surfaces of a ceramic block and a steel plate; thirdly, preparing a soldering assembly piece; and finally, performing temperature increment and soldering stage by stage to obtain the abrasion-resistant ceramic lining plate. The abrasion-resistant ceramic lining plate of the invention cancels a rubber layer, and improves the bonding strength, abrasion resistance and high-temperature service life; the shearing strength of soldering seams reaches 191MPa; the low temperature reduction rate reduces the residual stress of the lining plate; and the lining plate is not easy to break and has prolonged service life. The obtained lining plate can be used as the abrasion-resistant lining plate for equipment such as bins, hoppers and the like in a coal-conveying and dust-discharging system of a heat power plant and a conveying and preparing system of the metallurgical steel industry.

Description

technical field [0001] The invention relates to a method for preparing a wear-resistant ceramic liner. Background technique [0002] In metallurgy, chemical industry, electric power and other raw material and fuel delivery systems, the most common problem encountered is the wear and tear of equipment, pipelines, silos and chutes. Commonly used wear-resistant linings include cast iron linings, manganese steel linings, and cast stone linings. Since the raw materials transported by metallurgical plants for ironmaking and steelmaking are mostly ore, coke, limestone and various alloy materials, they have serious wear and tear on equipment linings, silo walls, and chute linings. The 16Mn steel liner with a thickness of 16mm is used in the system, and the bottom of the chute will be worn through after only half a month of use. The 16mm thick 16Mn steel lining used in the coal handling system of large and medium-sized coal-fired power plants was worn out after only 3 to 6 months o...
