Non-ferrous metal line rolling slag flushing channel

Abstract

The invention discloses a non-ferrous metal line rolling slag flushing channel which comprises a front rolling channel, a rear rolling channel and an external discharging area rolling channel. The front rolling channel is located in a heating furnace and high-pressure water scale removing area; the rear rolling channel is located in a hot rolling mill and mill-front mill-rear area; the external discharging area rolling channel is located in a confluence external discharging area; the front rolling channel, the rear rolling channel and the external discharging area rolling channel are each internally provided with a front passage, a rear passage and an external discharging area passage; the front passages, the rear passages and the external discharging area passages communicate in a Y shape; the front end of the heating furnace and high-pressure water scale removing area is provided with a front water spraying point; the rear end of the hot rolling mill and mill-front mill-rear area is provided with a rear water spraying point; and the rear end of the confluence external discharging area is provided with a rotational flow well and a sedimentation tank. The automation degree and the continuity degree are high, the treatment effect of wastewater containing scales is good, and energy saving and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metals, in particular to a slag flushing ditch for a nonferrous metal rolling line. Background technique [0002] With the rapid development of economy and society and the continuous progress of metallurgical technology, the production of non-ferrous metal hot-rolled plates and strips is increasingly developing in the direction of large-scale, high automation, high cleanliness and high surface quality. The process and engineering design of hot rolling production lines put forward higher requirements. [0003] Since the ingot is in a high temperature state (generally 600-1100°C) during the heating and hot rolling process, non-ferrous metal plates and strips such as copper and copper alloys, titanium and titanium alloys, nickel and nickel alloys are processed by hot rolling mills. When it is produced, it is necessary to consider the removal of surface scale, thereby improving the surface quality...

Problems solved by technology

However, the collection and treatment of scale wastewater in the above-mentioned form has the following problems: high energy consumption, large investment, and high maintenance costs in the later period; most of the scale is deposited under the foundation pits, and it is necessary to manually enter the pits at regular intervals for cleaning. The degree is low, the labor intensity is high, and there are many safety hazards
