Method for construction of multi-point integral top pulling steel case beam

The invention discloses a construction method of a multi-point whole incremental launching steel box girder, which belongs to the field of bridge engineering. The construction method uses a dental plate with a tooth socket, which is arranged on a steel box girder and a guiding beam web plate, a jacking force is supplied by an incremental launching jack, wherein a piston rod of the incremental launching jack is equipped with a slider, on which a spinous block with an inclined plane and a control spring are arranged, the inclined plane is arranged on the side of the incremental launching jack, the steel box girder and the guiding beam are applied with the jacking force through the push travel of the incremental launching jack, and the spinous block withdraws from the tooth socket during the return to enter into a next push travel. The construction method also supplies the support and adjusts the elevation of corresponding points through lifting-up the jack, simultaneously the incremental launching jack and the upper portion of the incremental launching jack are all equipped with a displacement sensor and a pressure sensor to collect information, thereby controlling an incremental launching process. The construction method has less consumption of steel material, a support reaction and a thrust force are capable of being controlled, and the problem of the rotation angle of the steel box girder is capable of being excellently solved.

Smelting process for controlling spring steel inclusions

The invention discloses a smelting process for controlling spring steel inclusions. The smelting process comprises the following steps of (1) KR molten iron desulfurization pretreatment, (2) BOF top-bottom double combined flowing converter smelting, (3) LF furnace refining, (4) RH furnace refining and (5) continuous casting process, wherein the mass fraction of S is controlled to be below 0.005% after molten iron is processed by the step (1); the step (3) is carried out by high-purity silicon carbide for diffusion deoxidation, and the refining slag alkalinity is controlled to be 0.6-0.9; a lowalkalinity slag process is adopted in the step (4), and the final slag alkalinity is 0.5-0.7; and it is ensured that a molten steel contact part is free of aluminum in the step (5), a double electromagnetic stirring process is adopted in a secondary cooling zone and a casting blank solidification end zone, and a central carbon segregation index is controlled to be below 1.15. The smelting processadopts molten iron pretreatment, converter catching carbon, refining low alkali slag, continuous casting protective pouring and special refractory materials. Through the control over the oxygen potential of molten steel, the inclusion form and the central carbon segregation, the spring drawing performance is improved, and the spring fatigue limit is increased.

Manufacturing method of shallow groove isolation structure

The invention provides a manufacturing method of a shallow groove isolation structure, which is used for manufacturing the shallow groove isolation structure. A silicon-on-insulator orderly comprises a silicon substrate layer, an oxidation buried layer and a monocrystalline silicon top layer. The manufacturing method of the shallow groove isolation structure comprises the following steps of: depositing a layer of silicon dioxide and silicon nitride on the monocrystalline silicon top layer to serve as a hard screening layer, coating photoresist and exposing for development, etching the hard screening layer by means of dry etching, removing the residual photoresist, and exposing the position on the monocrystalline silicon top layer for manufacturing the shallow groove isolation structure; and performing oxygen ion implantation from upward side of the monocrystalline silicon top layer and annealing at high temperature to form a silicon dioxide isolation zone on the monocrystalline silicon top layer. The manufacturing method of the shallow groove isolation structure provided by the invention is not required to perform silicon dioxide deposition and chemical mechanical polishing to the shallow groove and can improve the component integration level so as to enhance the integration level, simplify the manufacturing flow and reduce the cost.
