Three-liquid double-phase double-metal-ZTA ceramic composite material impact crusher plate hammer and manufacturing method thereof

Abstract

The invention discloses a three-liquid two-phase bimetal-ZTA ceramic composite material impact crusher plate hammer and a manufacturing method thereof.The three-liquid two-phase bimetal-ZTA ceramic composite material impact crusher plate hammer comprises martensitic steel, high-chromium cast iron and a high-chromium cast iron-ZTA composite cylinder, the martensitic steel is located in the middle, the high-chromium cast iron is located on the two sides of the martensitic steel, and the high-chromium cast iron-ZTA composite cylinder is located on the outermost side of the high-chromium cast iron; the high-chromium cast iron-ZTA composite cylinder is formed in the mode that high-chromium cast iron powder is melted and connected in a bridging mode to evenly wrap ZTA, the high-chromium cast iron-ZTA composite cylinder is evenly embedded into a mold in advance, and in the high-chromium cast iron molten iron casting process, the high-chromium cast iron-ZTA composite cylinder is formed in the mode that high-chromium cast iron powder is melted and connected in a bridging mode to evenly wrap ZTA. And the high-chromium cast iron-ZTA composite cylinder is automatically embedded into the high-chromium cast iron on the outermost side. The high-chromium cast iron and the martensitic steel are bonded in a diffusion metallurgical mode, and the high-chromium cast iron and the high-chromium cast iron-ZTA composite cylinder are bonded in a diffusion metallurgical mode. According to the plate hammer of the impact crusher, the martensitic cast steel, the high-chromium cast iron and the ZTA ceramic are organically combined in a mutual gradient mode, and ultrahigh wear resistance is obtained.

Description

technical field [0001] The invention belongs to the field of mining engineering machinery crushing, and particularly relates to a method for manufacturing a plate hammer of a high-strength and high-wear-resistance impact crusher. Background technique [0002] The blow hammer of the impact crusher is a key part installed in the continuous crushing station, which realizes the crushing of the demolition of mines, buildings and road facilities. The impact crusher plate hammer is responsible for hitting, shearing and wearing broken objects, medium manganese steel, medium and low alloy steel or martensitic steel, high chromium cast iron, etc., adopting integral casting, bimetal casting, metal surface strengthening (surfacing welding) , casting infiltration, etc.). In view of the insufficient service life, the ceramic composite blow hammer has become a development trend. [0003] In the manufacture of impact crusher blow hammers from ceramic composite materials, ZTA ceramics with...
