Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0034] Depend on Figure 1-2 , a casting method of a steel-copper composite cylinder, comprising the following steps:

[0035] Step 1. Establish a three-dimensional model, calculate the mass of the cast copper metal to be 19.86kg, carry out casting process design and simulation, optimize the casting process, and determine that the initial temperature of the steel base is 1250°C, and the initial casting temperature of the copper metal is 1250°C. The holding time is 9-12min, the casting time is 15s, and the casting speed is 1.5kg / s;

[0036] Step 2: Use cylindrical steel billet as the steel base, and perform heat treatment and annealing process on the steel base: slowly heat to 900°C-1050°C, heat for 15h-20h and then cool to room temperature;

[0037] Step 3: Carry out turning, mil...

Abstract

The invention discloses a casting method for a steel-copper composite cylinder body. The casting method comprises the steps of performing three-dimensional modeling, designing a casting technology and performing technology simulation and optimization, performing base steel heat treatment, performing machining, tool machining and welding, performing base steel surface treatment, performing pre-heating treatment before base steel production, smelting copper alloy, dipping the copper alloy, melting anhydrous borax, putting base steel into a borax solution, pouring the copper alloy into the base steel, putting the base steel into a water tank and cooling and solidifying the base steel to room temperature to obtain the steel-copper composite cylinder body. According to the casting method, the problems of the composite casting technology and the composite material composition of the steel-copper cylinder body can be solved; and the composite strength of the thermometal cylinder body can be high, the yield can be high, the cost can be low, the size of the cylinder body can not be limited, the forming process can be controlled easily, and the quality can be stable.

Description

technical field [0001] The invention is applied to the field of metal casting, and in particular relates to a casting method of a steel-copper composite cylinder body. Background technique [0002] In the field of casting, the casting technology of steel-copper-metal composite is not mature and stable all the time. For a long time, welding or powder sintering methods have been used for production, but both methods have many limitations. If the welding compound is not strong, the metal will often fall off and the service life will be short; the size of the powder sintering molding cannot be too large, and the cost is very high. Through the understanding of advanced countries, the steel-copper composite cylinder block produced by casting method is the most reliable. There is a great demand for domestic steel-copper composite cylinders, but most of them still rely on imports, and most of the imported composite cylinders are produced by casting. The steel-copper composite cyl...
