Abstract

The invention discloses a continuous casting thermal compound device which comprises a bracket, a steel plate conveying device fixedly connected with the bracket, a sealing and heating device, an alloy metal thermal-insulation device, an alloy layer rolling and leveling device, a cooling device, a rolling roll device and an alloy melting device; an outlet at the bottom of the alloy metal thermal-insulation device is communicated with a chute runner at the top of a steel plate conveyer belt; an ultrasonic device is arranged below the chute runner; the cooling device is composed of multi-row orientated nozzles; all parts are regulated by a control system. The continuous casting thermal compound device is utilized for continuous casting and thermal compound of the copper lead alloy and the steel to produce a bimetallic bearing material; the copper lead-steel bearing material produced by the device of the invention has slender alloy structure, where the lead shows a short-shoot shape and a small part thereof has a shape of ball and is distributed uniformly on the copper matrix, without net-like structure or discontinuous net-like structure; the bearing material also has good homogeneity of structure, with relatively high bonding strength between duplex metals and stable and reliable quality.

Description

technical field [0001] The invention belongs to the technical field of metal material forming and processing, and in particular relates to a bimetal material continuous casting thermal composite device, and also relates to a method for preparing a copper-lead alloy-steel bearing material by using the device. Background technique [0002] Copper-lead alloy-steel bearing pad material is the blank for manufacturing bearing pads. It uses a steel plate as the back of the pad and a copper-lead alloy as the lining. Under certain conditions, the copper-lead alloy and steel are combined, that is, a layer of copper-lead is cast on the steel plate. Alloy, which constitutes copper-lead alloy-steel bimetallic bearing material; the components of the bearing material complement each other to form excellent comprehensive performance, and are widely used in the manufacture of high-performance internal combustion engine bearings such as ships, aviation, and automobiles. [0003] At present, t...
