The invention relates to wear-resistant steel and belongs to the technical field of metal smelting. The wear-resistant steel is prepared from the following components in percent by mass: 0.88-0.94% ofC, 0.20-0.30% of Si, 0.90-1.00% of Mn, 0.50-0.60% of Cr, 0.20-0.60% of W, 0.10-0.25% of V, 2.50-3.00% of Zr, 0.010-0.050% of Ti, 0.020-0.050% of Y, less than or equal to 0.025% of P, less than or equal to 0.025% of S, less than or equal to 0.25% of Cu and the balance of Fe and inevitable impurities. The wear-resistant steel has the beneficial effects that the problems of low strength and poor wear resistance of the existing low-carbon wear-resistant steel is solved; the wear-resistant steel is finer in crystal and fuller in internal density, and a grinding ball prepared by the wear-resistantsteel is larger in hardness and good in wear resistance.

A tool for filling liquid electrolyte in an electrolytic tank, including a chute and a chute cover covering the top of the chute. The baffle plate and the rear side baffle plate are composed of a slide pipe along the axis of the bottom plate in the tank shell. A pair of hooks are respectively provided at the front and rear ends of the left and right baffle plates. The left side baffle plate between the two hooks There are vertical pipes at intervals on the board. The chute cover is composed of left and right cover plates. The two cover plates are connected by a connecting pipe and arranged symmetrically relative to the connecting pipe. The two cover plates form an included angle, 60°≤the The included angle is less than or equal to 150°. There are vertical support rods at intervals on the left side of the left cover plate. The distance between the two support rods is equal to the distance between the two pipes. The two support rods are located in the two pipes. Advantages: It reduces the splash loss of liquid electrolyte, avoids the burning of the gantry column and insulating plate of the electrolyzer, and ensures the safety of the personnel involved in the start-up of the electrolyzer on site.

The invention discloses an alternate absorbing core of staggered horizontal tube bundles and ripple screen mesh layers. The ripple screen mesh layers are inserted among horizontal tube bundles of the staggered horizontal tube bundles; the cross-section shapes of the ripple screen mesh layers are in a trapezoidal wave shape, and the adjacent ripple screen mesh layers are symmetrical relative to the clamped horizontal tube bundles; the upper edge and lower edge of the ripple screen mesh layer trapezoidal wave are respectively arranged on the lower part of an upper-layer heat transferring tube and the upper part of a lower-layer heat transferring tube of the ripple screen mesh layer trapezoidal wave; the folding line direction of the ripple screen mesh layer trapezoidal wave and the direction of the heat transferring tubes are the same; the ripple pitch of the trapezoidal wave is equal to the horizontal tube center distance of each horizontal tube bundle; a formed liquid membrane orderly passes through an alternate caloric transmitting structure of the horizontal tube bundles and the ripple screen mesh layers. The alternate absorbing core has the advantages that the absorbing area of the absorbing core is enlarged, furthermore the solution mixing is promoted, and the solution surface is kept continuing relatively strong in absorbing driving power, so that en effect that a reinforced solution absorbs cryogen steam is realized.

The invention relates to the technical field of industrial metallurgical smelting equipment, in particular to furnace heat exchange type electric arc metallurgy equipment for smelting various special alloys. The equipment comprises an air compressor (1), a mixing cylinder (2), a feed hopper (3), a main pipe (4), hollow electrodes (5), an electric furnace (6), electric arc areas (7), branch pipes (8) and a feeding pipe (9). The equipment is characterized in that one end of the mixing cylinder (2) is fixedly connected with a smelting device through the main pipe (4) while the other end is connected with one end of the air compressor (1) fixedly, one side of the mixing cylinder (2) is fixedly connected with the feed hopper (3) through the feeding pipe (9), the smelting device comprises the hollow electrodes (5), the electric furnace (6), the electric arc areas (7) and the branch pipes (8), and one end of each hollow electrode (5) is in through connection with the main pipe (4) through the corresponding branch pipe (8).

A bearing housing (1) of an exhaust-gas turbocharger, having a compressor-side housing flange (2), a central housing section (3) which is integrally connected to the housing flange (2) and in which is arranged a first partial section (4) of an oil chamber (5) which has an oil inlet (20) and an oil outlet (21), and a turbine-side housing section (6) which has a turbine-side housing flange (7) and in which is arranged a second partial section (8) of the oil chamber (5). The central and turbine-side housing sections (3, 6) are provided with an oil cooling duct (13; 13′).

In a load shift transmission for a utility vehicle having a transmission input shaft, a split group, a main group and a range group, a dual clutch with two input shafts, a main shaft and a countershaft with input constants including loose gear wheels, one loose gear wheel of an input constant is selectively rotationally fixedly connectable by means of shift elements to either one of the input shafts which can in each case be coupled by means of clutches (K1,K2) to the main transmission input shaft, the countershaft can be driven by one of three input constants with power being transmitted via the countershaft in all forward gears with the exception of a direct gear. The arrangement provides, with a simple design, for the possibility to carry out sequential shifts and multiple up-shifts and multiple down-shifts without an interruption in traction force.
