The invention belongs to the field of mineral processing, and particularly relates to a filtration-integration integrated device and method for producing aluminum oxide by a Bayer process. In the device, a crude liquid tank is connected with a leaf filter through a crude liquid pump, the bottom of the leaf filter is connected with a filter cake tank, and the upper part is connected with a fine liquid tank; the bottom of the fine liquid tank is provided with a fine liquid pump; the fine liquid pump is connected with a vertical disk filter; the filter cake tank is arranged on a 5.000 plane; the lower part of the filter cake tank is provided with a filter cake pump; an aluminum hydroxide slurry tank is arranged above a horizontal disk filter; and the horizontal disk filter is connected with a belt conveyor. The device for aluminum oxide filtration provided by the invention implements filtration-integration integration. The invention reduces the crystal seed tank, mixing unit and other units in the existing device, reduces the corresponding pipelines, valves, pipe fittings and the like, reduces the equipment maintenance and maintenance work load in the device operation process, saves the energy, and lowers the production and labor cost.

The invention provides a method for treating secondary lead through an improved side-blowing smelting reduction furnace. The method comprises the steps that the secondary lead is put into the improved side-blowing smelting reduction furnace, meanwhile, a smelting agent is added, oxygen-enriched gas, a reduction agent and fuel are sprayed into a smelting pool mixing area of the smelting reduction furnace at the flow speed of 180-280 m / s through multichannel spray guns on the two sides of the smelting reduction furnace, so that materials in the smelting reduction furnace are subjected to a smelting reduction reaction, and wet lead and smelting slag are generated; the wet lead and the smelting slag are included in the smelting pool mixing area at the same time; and the smelting slag is discharged out of a slag outlet of the smelting reduction furnace, and the wet lead is discharged out of a metal discharge opening of the smelting reduction furnace. The method for smelting the secondary lead is compact in procedure, small in fixed number of workers, environment-friendly and low in production cost.

The invention discloses high-magnetic-strength low-cost cold-rolled magnetic pole steel with the yield strength being 450 MPa and a manufacturing method thereof. The steel comprises, by mass, 0.05%-0.09% of C, 0.75%-1.15% of Mn, no more than 0.025% of P, no more than 0.01% of S, 0.015%-0.05% of Al, no more than 0.01% of N, 0.005%-0.02% of Nb, 0.05%-0.09% of Ti, and the balance Fe and inevitable impurities; and the content of Ti is larger than or equal to 0.03%+3.43*N. The high-magnetic-strength low-cost cold-rolled magnetic pole steel is simple in chemical component, and the cost is greatly lowered due to adding of the cheap Ti; the continuous annealing mode is adopted, the product performance uniformity is obviously improved, the lower yield strength ReL of the manufactured magnetic pole steel is higher than or equal to 450 MPa, and the magnetic induction intensity B50 of the manufactured magnetic pole steel is higher than or equal to 1.6 T; the steel plate strength and the magnetic induction strength are well matched, and the product has more excellent comprehensive performance.

The invention relates to a method for detecting raw anode carbon blocks, in particular to a method for detecting raw anode carbon blocks based on machine vision for the intelligent production of carbon plants. A green anode carbon block detection method based on machine vision. Cameras are set at the outlet of the carbon block forming machine in the forming workshop to collect images of carbon blocks from multiple angles. The cameras collect images of each surface of the carbon block, and then perform offline modeling and online detection; The offline modeling consists of two parts: the modeling of the top surface of the carbon block and the modeling of the remaining five surfaces; the online detection includes the detection of the top surface of the carbon block, the detection of the remaining five surfaces of the carbon block, and the judgment strategy of the qualified carbon block. The advantages and effects of the present invention: 1. The carbon block detection link in the forming workshop is intelligent, which reduces the labor quota; 2. The carbon block detection based on machine vision implements a unified standard, which is not affected by human subjective consciousness and personnel status, and the detection results are more accurate. Accurate; 3. This method can store the results of carbon block detection in the database, and provide data support for the MES system of the whole plant.

A process for cleaning the crude gas coming from the coal-pyrogenous furnace includes such steps as gas-liquid separation, cooling, capturing tar oil, removing benzene and naphthelene, desulfuring, conveying gas, and saturating to remove ammonia and obtain clean gas.
