The invention discloses a technique for using calcium carbonate carbon spheres in LF (ladle furnace) steelmaking, which comprises the following steps: pulverizing limestone to the granularity of 1mm below, evenly mixing with graphitic carbon, and pressing with a dry powder sphere presser to obtain calcium carbonate carbon spheres, wherein when producing every 100kg of calcium carbonate carbon spheres, the addition amount of limestone is y (y=83(100beta-51) / (83beta-12gamma)), the addition amount of the graphitic carbon is 100-y, beta is the carbon content (%) in the graphite, and gamma is the calcium carbonate content (%) in the limestone; and when smelting aluminum killed steel in a converter, adding the calcium carbonate carbon spheres according to the principle of equal addition amount to the substituted traditional calcium carbide, and using according to the traditional steelmaking technique.

The invention discloses a stacking and transporting device for an integral type side wall of a car. The stacking and transporting device comprises a frame. An upper component of the rear side of the frame is connected with an upper side wall supporting rod horizontally arranged. The upper side wall supporting rod is connected with a trapezoid-shaped groove rubber strip matched with the upper edge of the frame of the side wall. A lower component of the frame is connected with a lower side wall supporting rod horizontally arranged. The lower side wall supporting rod is connected with a Y-shaped groove rubber strip matched with the lower edge of the frame of the side wall. The middle of the right side of the frame is provided with a right cross rod. The inner side of the right cross rod is connected with a concave rubber strip matched with the right edge of the side wall. The middle of the left side of the frame is provided with a left cross rod connected with a left locating rod. The end portion of the left locating rod is provided with a Y-shaped branch and provided with a rubber sleeve. The upper portion of the front side of the frame is of an open structure. The two sides of the frame are provided with hauling mechanisms. Each hauling mechanism is composed of a hauling frame connected to one end of the frame and a hauling base connected to the other end of the frame. The upper ends of stand columns of the four corners of the frame are provided with guiding and locating sleeves. The lower sections of the guiding and locating sleeves are provided with guide sleeves in a horn-mouth shape, and the upper sections of the guiding and locating sleeves are provided with locating sleeves in a square straight cylinder shape. The stacking and transporting device can be applied to the processes of manufacturing, storing and transporting parts of the integral type side wall of the car, and has the advantages of being convenient in location and easy to manage, and preventing impact.

The invention discloses a tool for brake caliper testing. The tool comprises a pedestal and an insert detachably fixed to the pedestal. A brake disc is detachably fixed to the pedestal, and a brake caliper is detachably fixed to the insert. An opening of the brake caliper is opposite to the center of the brake disc. Compared with the prior art, the tool for brake caliper testing is designed through a modular thought, the insert is detachably fixed to the pedestal, and the brake caliper is simultaneously detachably connected with the insert; and the different inserts are manufactured to meet the needs for the brake calipers of different specifications, so that the universality of the tool is achieved, reduction of the tool manufacturing cost and shortening of the tool manufacturing period are facilitated, and meanwhile, tool warehouse management is facilitated.

The invention discloses a process of using magnesia-calcium-carbon balls in LF (ladle furnace) steel making. The process comprises the steps that dolomite and graphite carbon are uniformly mixed, then crushed, and pulverized till the particle size is below 1mm; the pulverized dolomite and graphite carbon are then put into a ball pressing machine to allow carbon, and calcium carbonate and magnesium carbonate that are in dolomite to be pressed together to form a homogeneous body of carbonate and carbon; and the homogeneous body is made into deoxidant carbon balls capable of replacing calcium carbide. Computational formulas of adding amounts of carbon and dolomite are as follows: (1) the content of carbon is controlled at 45%, the content of carbon in dolomite is assumed to be alpha, the content of carbon in graphite is assumed to beta, the adding amount of graphite is Q, then the computational formula of the adding amount (Q) of graphite is as follows: Q is equal to (45-100alpha) / (beta-alpha); and (2) the adding amount (G) of dolomite is controlled in accordance with 100-Q. When aluminium killed steel is smelted in a rotary furnace, according to the principle of replacing calcium carbide at the equal adding amount, the above deoxidant carbon balls are added, and are used according to the traditional steel melting process.

The invention relates to an integrated thermomagnetic system bracket of a small circuit breaker, which comprises a static contact plate, a magnet yoke and a double-metal positioning piece. The magnet yoke is located between the static contact plate and the double-metal positioning piece. The static contact plate, the magnet yoke and the double-metal positioning piece are integrally structured. The magnet yoke comprises a conductive part and a magnetic inductive part. The conductive part is made of a metal conductive material and the magnetic inductive part is made of a ferro magnetic material. According to the thermomagnetic system bracket provided by the invention, the static contact plate, the magnet yoke and the double-metal positioning piece are integrally structured so that the number of parts is reduced, the stability of a magnet yoke magnetic field is enhanced, and the stability of a tripping mechanism of the circuit breaker is improved. At the same time, the cost of the magnet yoke is saved according to dual functions of the magnet yoke where current passes through and which generates the magnetic field, so that the thermomagnetic system bracket as a whole is simpler, and further, the defect that conventional bracket welding leads to deformation of the bracket can be avoided.
