The invention relates to the field of neodymium-iron-boron production and processing, in particular to a neodymium-iron-boron bar directional arranging and feeding device. The invention aims to provide the neodymium-iron-boron bar stock directional arranging and feeding device which is high in automation degree, lossless in conveying and capable of improving the yield and the production efficiency through online screening. A neodymium-iron-boron bar stock directional arranging and feeding device comprises a main frame, and three bar stock conveying belts are installed on the top of the main frame. A connecting frame is fixedly connected to the right of the upper side of the main frame, and a mounting frame is fixedly connected to the left of the upper side of the main frame. The device integrates the functions of automatic mounting, accurate positioning, pushing-out, conveying, detecting, screening, pushing-in, crushing and discharging, the whole-process automatic operation of taking out neodymium iron boron bars from neodymium iron boron forming molds and accurately loading the neodymium iron boron bars into rubber molds is achieved, the traditional operation mode of manually taking, placing and arranging the bars is not needed, the production efficiency is improved, and the production cost is reduced. And meanwhile, the labor intensity and the labor cost are remarkably reduced.

This invention relates to a forging method for stepped gear shafts from continuously cast billets with diameters of φ600~φ785mm. The method involves loading the continuously cast billet into a heating furnace, holding it at 700~800℃, and then raising it to 1230℃±10℃. The billet is then upset with the tail end facing upwards using a concave upsetting plate, with an upsetting height-to-diameter ratio of 0.6~0.7. The billet is then drawn on an upper and lower flat plate, with a reduction of 13~18% per pass, and rotated 90° per pass. Finally, the billet is drawn on upper and lower flat anvils, with a reduction of 18~22%, and fed into the anvils at full capacity, ensuring at least one [unclear unit] per two anvils. With a 5% anvil loading, the anvil is rotated 90° per pass. A 3150-ton hydraulic press is used to upset the riser end with a concave upsetting plate, resulting in a height-to-diameter ratio of 0.6 to 0.8. The billet is drawn to be 20 to 30 mm larger than the maximum step diameter of the stepped gear shaft. After scoring, the billet is kept at a furnace temperature of 1030±10℃. The small steps at both ends are forged into finished products, and the large steps are forged into finished products within the range of 760℃ to 790℃. This improves the actual grain size and banded structure qualification rate of the stepped gear shaft, reduces the need for one normalizing step, and improves the low-magnification structure.

The application discloses a kind of nuclear power gate valve body molten steel filtering device, including liquid injection tank, the upper end of the liquid injection tank is installed with the liquid inlet channel being communicated with its inside, and the liquid inlet channel is embedded with baffle, two porous ceramic filter plates are arranged in the liquid injection tank, the liquid outlet channel being communicated with its inside is installed on the both sides of the liquid injection tank, the lower end of the baffle is fixedly connected with support by telescopic link, and the side wall of the support is rotatably connected with arc-shaped cylinder.The filter residue on the liquid level is gently scooped up by the arc-shaped cylinder and flows into the liquid storage hopper for temporary storage, and then discharged outward through the discharge hopper and the discharge pipe, so that the molten steel in the liquid injection tank does not flow substantially, which can more effectively and completely clean the filter residue on the liquid level, without increasing the outflow speed of the molten steel, ensuring that the molten steel in the mold is in a stable state, and improving the processing quality of the final valve body casting.
