Embodiment Construction
[0009] The homogenization treatment method of the copper-based catalyst alloy ingot for scale inhibition of the present invention, the components are Cu, Ni, Zn, Sn, Pb, Fe, Sb, Mn eight kinds of metal elements, and the weight percentage of each component is: Cu40%-70%; Ni5%-20%; Zn10%-35%; Sn5%-30%; Pb0.5%-20%; Fe0.1%-8%; Sb0.01%-2%; The copper-based catalyst alloy ingot is homogenized with a resistance heating furnace, and the specific steps are as follows:
[0010] Clean the hearth of the heat treatment resistance furnace, put the copper-based catalyst alloy ingot into the hearth at room temperature, turn on the furnace to heat up, and raise the temperature to 700°C-850°C at a heating rate of 30°C / s-50°C / s , keep warm for 60min-90min, then raise the temperature to 1000℃-1150℃ at a heating rate of 10℃ / s-30℃ / s, keep warm for 300min-360min, turn off the power, let the metal ingot cool down with the furnace to 300℃-400℃, turn on Furnace door, take out the copper-based catalyst...

Abstract
The invention discloses a homogenization processing method of a copper-based catalyst alloy ingot for inhibiting scale, the core technology is a two-stage temperature processing method: heating to 700DEG C to 850 DEG at a speed of 30 DEG C per second to 50 DEG C per second, keeping the temperature for 60 minutes to 90 minutes, and then heating to 1000 DEG C to 1150 DEG C at a speed of 10 DEG C per second to 30 DEG C per second, keeping the temperature for 300 minutes to 360 minutes, cutting off the powder, furnace cooling the metal ingot to 300 DEG C to 400 DEG C, opening the furnace door, getting out the copper-based catalyst alloy ingot and air cooling to room temperature. By this processing method, a columnar crystal orientated growing along S100 crystal axis inside of the copper-based catalyst alloy is formed, which can not only prevent scale from growing, but also dissolve scale.
Description
Technical field: [0001] The invention relates to a processing technology for a copper-based catalyst alloy material with an anti-scaling function, in particular to a homogenization treatment method for a copper-based catalyst alloy ingot. Background technique: [0002] In the water treatment process of petroleum, chemical industry, electric power, papermaking, printing and dyeing, heating and other industries, as well as in the process of water heating, water pipelines must be used. Water pipelines will produce scale during long-term high-temperature use. This substance The occurrence of these accidents will affect the normal operation of industrial production in light cases, and cause major safety accidents such as paralysis of the entire production system or explosion of equipment in severe cases. For this reason, after long-term experimental research, our unit has finally developed a copper-based catalyst alloy material with anti-scaling function. Its components are Cu, N...
