Embodiment 1

[0007] Take 92.8 kg of copper, put the copper into a smelting furnace for heating and smelting, after melting, add charcoal, charcoal is generally suitable to cover the surface of copper water by 8~10 cm, the temperature is 1080 degrees, then add 7 kg of tin, phosphorus 0.2 kg, continue to smelt, the temperature rises to 1150 degrees, heating while smelting, after smelting, when it reaches 1240 degrees, it is released from the furnace, and the bronze water released from the furnace is cast into bronze ingots by the horizontal continuous casting method.

Embodiment 2

[0009] Take 93.9 kilograms of copper, put the copper into the smelting furnace to heat and smelt it, and then add charcoal after it is smelted and melted. The charcoal is generally suitable to cover the surface of the copper water by 8 to 10 centimeters, the temperature is 1100 degrees, and then add 6 kilograms of tin, phosphorus 0.1 kg, continue to smelt, the temperature rises to 1140 degrees, heating while smelting, after smelting, when it reaches 1200 degrees, it is released from the furnace, and the bronze water released from the furnace is cast into bronze ingots by horizontal continuous casting method.

Embodiment 3

[0011] Take 93.25 kilograms of copper, put the copper into the smelting furnace for heating and smelting, after melting, add charcoal, charcoal is generally suitable to cover the surface of copper water by 8~10 cm, the temperature is 1080 degrees, and then add 6.5 kg of tin, 0.25 phosphorus kg, continue to smelt, keep the temperature at 1080 degrees, keep the temperature while smelting, and release the furnace after smelting. The bronze water released from the furnace is cast into bronze ingots by horizontal continuous casting method.

Abstract

The invention relates to a bronze ingot, which is characterized by consisting of the following components in percentage by weight: 6-7 percent of tin, 0.1-0.25 percent of phosphorous and the rest of copper, and is further characterized by consisting of the following components in percentage by weight: 7 percent of tin, 0.2 percent of phosphorous and 92.8 percent of copper. A method for producing the bronze ingot is characterized by comprising the following steps of: feeding copper into a furnace; igniting and heating to 1,080-1,110 DEG C; adding charcoal for smelting; adding tin and phosphorous into a smelting furnace for continually smelting and heating to 1,080-1,150 DEG C; discharging after the temperature rises to 1,180-1,240 DEG C after smelting; and discharging and casting bronze ingots with a horizontal continuous casting method. The method is characterized in that: the thickness of the charcoal covered on copper water is generally 8-10 centimeters. The bronze ingot has the advantages that: a Spectro direct-reading spectrometer made in Germany is used for performing complete analysis on the copper water before smelting a dummy ingot, and an atom absorption spectrophotometer is used for rechecking a sample, so that the components of the copper water are completely qualified and accurate.

Description

technical field [0001] The invention relates to a bronze ingot. Background technique [0002] Bronze ingots are widely used in the foundry industry for turning sand, casting valve fittings, turbine worms, bearing bush sliders, etc. At present, the semi-continuous casting method is mostly used to produce ingots of various specifications. The product yield is low, and the surface of the ingot is rough, which is prone to reverse segregation. Therefore urgently need existing bronze ingot to be improved, to solve the existing problem of current bronze ingot. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the bronze ingot in the prior art, and to provide a bronze ingot. The present invention designs a bronze ingot, which is characterized in that it is composed of the following components by weight percentage: tin 6-7%, phosphorus 0.1-0.25%, copper balance. It is characterized in that it consists of ...
