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

A casting method for a steel-copper compound cylinder includes the steps of three dimensional modeling, casting technology design and technology simulation and optimization, steel base heat treatment, machining-tool machining and welding, steel base surface treatment, preheating treatment of the steel base before production, borax leaching, copper alloy smelting, pouring the copper alloy into the steel base, centrifugal treatment and cooling solidification to the room temperature, and obtaining the steel-copper compound cylinder. The casting method solves the difficult problems of compound casting technology and compound material elements of the steel-copper cylinder; and the compound strength of the bi-metal cylinder is high, the rate of finished products is high, the cost is low, the size of cylinders is not limited, the molding process is easy to control, and the quality is stable.

Description

technical field [0001] The invention is applied in 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...
