The present application relates to a kind of modular molten salt loading and storage system, including vertical support structure rack, normal temperature electrical equipment group and high temperature molten salt equipment group are physically separated by isolation fence and integrated in it;High temperature molten salt equipment group includes molten salt storage tank and molten salt pipeline connected with molten salt storage tank;Molten salt pipeline includes molten salt loading pipe, molten salt loading pipe has upward inclination relative to horizontal plane, to realize the self-weight backflow of molten salt;The middle section of molten salt loading pipe is connected with molten salt isolation valve, and molten salt isolation valve and normal temperature electrical equipment group are cooperated to realize the on-off control of molten salt loading pipe.The present application effectively avoids the thermal influence of high temperature environment on normal temperature electrical equipment by isolation fence, and the integrated design of overall modularization integrates the core equipment of molten salt loading and storage into one, discards the traditional dispersed equipment arrangement and installation mode, greatly simplifies the field construction process, reduces installation period, also makes the debugging, maintenance and overhaul of system more convenient.

The invention belongs to the field of cutter machining equipment, and relates to a cutter handle shaping device and a cutter handle shaping method. The problems that in the prior art, due to split type operation and manual transfer, temperature drop is too large, and the shaping quality is not stable are solved. The device comprises a cutter conveying assembly, a heating assembly and a pressing assembly. A first position for heating and a second position for pressing are sequentially arranged on a guide rail of the cutter conveying assembly. The cutter conveying assembly is used for driving the cutter to be transferred from the first position to the second position for press-fit shaping after heating is completed. The heating process and the pressing process are integrated on the same automatic platform, the process transfer time is shortened, temperature drop of the cutter handle in the transfer process is restrained, and therefore the quality stability and consistency of final products are improved.

The application discloses a casting method of a cast-state QT700-3 gear hub, and comprises the following steps: step one, determining the placing state of the gear hub in the sand mold as a placing mode with a small opening downward and a large opening upward; step two, determining that one gear hub is placed in the sand mold of each sand box; step three, determining a riser structure, the riser is designed to be integrated with the gear hub, the cross section of the riser extends along the large opening direction of the gear hub, and the cross section is Y-shaped; step four, determining that the parting mode of the gear hub during casting is horizontal parting along the top of the riser of the gear hub, and the sand mold is divided into two parts; and step five, determining a gating system structure, the sprue gate and the runner are located on the upper sand mold, and the position, at which the top of the sprue gate is connected with the outside of the mold, is a funnel-shaped top structure of the sprue gate. The casting method of the cast-state QT700-3 gear hub can reduce casting defects such as inclusions, pores and loose in the gear hub during the casting process, improves the internal quality of the gear hub, and meets the performance requirements of the QT700-3 material in the cast state.
