Abstract

The invention discloses a composite guide plate with a surface sprayed layer, comprising a guide plate, a plurality of first slide grooves are arranged on the working connecting surface of the guide plate, and the upper end of the first slide groove is also provided with a The first limit groove, the upper end of the working connecting surface is also provided with a working block, and the upper end surface of the working block is also coated with a wear-resistant coating, and the wear-resistant coating is made of the following materials: the composite in the present invention The guide plate is rubbed by spraying a wear-resistant layer instead of the guide plate to prevent the wear of the composite guide plate due to friction, and the sprayed coating used in the present invention has good wear resistance, and the preparation process is simple. The material used is environmentally friendly; the sprayed layer is used to replace the composite guide plate to prevent the composite guide plate from being too short in service life, resulting in the defect of a large amount of consumption of the guide plate; and through the setting of the working block, the invention can use the working block to perform friction , and the working block is easier to replace and maintain than the guide plate.

Description

technical field [0001] The invention belongs to the field of composite guide boards, and relates to a surface spray coating technology, in particular to a composite guide board with a surface spray coating. Background technique [0002] The guide plate is an important part in steel rolling, and its service life directly affects the output of steel. The guide plate used in China is usually made of nickel-chromium (nickel-based) alloy, high-chromium cast iron or ordinary cast iron as a whole. It has been measured that when the billet passes through the guide plate, the temperature at 2mm below the contact surface reaches 720°C, and the temperature at 1mm below the contact surface reaches above 800°C. Because the guide plate bears the strong friction, impact and thermal alternating stress of the hot billet, it is difficult for the integral casting material to meet the requirements for the hardness and toughness of the guide plate at the same time; the high hardness material is...
