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, and 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 8-10 centimeters, and 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, the 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. The bronze ingot is characterized by consisting of the following components in percentage by weight: 6-7% of tin, 0.1-0.25% of phosphorus, and the balance of copper. The bronze ingot is characterized by consisting of the following components in percentage by weight: 7% of tin, 0.2% of phosphorus, and 92.8% of copper. A preparation method of the bronze ingotis characterized by comprising the following steps: firstly, copper is fed in a furnace, and is ignited for heating to 1080-1100 DEG C; charcoals are added for smelting; then, tin and phosphorus areput in a smelting furnace for continuous smelting to enable the temperature to reach 1080-1150 DEG C; after smelting, the temperature reaches 1180-1240 DEG C; then, the bronze ingot is discharged fromthe furnace; and the bronze ingot is cast by adopting a horizontal continuous casting method. The preparation method of the bronze ingot is characterized in that the charcoals generally cover the surface of molten copper by 8-10 cm. The preparation method of the bronze ingot has the following advantages: a Speicher direct reading spectrometer made in Germany is adopted to comprehensively analyzethe molten copper before smelting of a dummy ingot; and an atomic absorption spectrophotometer is adopted to recheck standard samples to guarantee totally qualified components of the molten copper andaccurate components.

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 ...
