Synthesis and preparation process for high-silicon-molybdenum ductile iron material

ActiveCN106222526AImprove brittle tendencyImprove mechanical propertiesSurface modeFerrosilicon
The invention relates to a synthesis and preparation process for a high-silicon-molybdenum ductile iron material. The synthesis and preparation process specially comprises the following steps that raw materials are prepared, and the raw materials comprise, by mass, 60%-70% of scrap steel, 25%-35% of cast iron, 1%-1.2% of silicon iron, 1%-1.3% of ferro-molybdenum and 2%-2.5% of carburant; in the raw material melting process, furnace burdens are added in three batches; all the cast iron and 1/3 mass part of scrap steel are added in the first batch of furnace burdens, 5/11 mass part of carburant and 1/3 mass part of scrap steel are added in the second batch of furnace burdens, and 5/11 mass part of carburant and 1/3 mass part of scrap steel are added in the third batch of furnace burdens; after the third batch of furnace burdens are completely molten down, all the silicon iron and ferro-molybdenum are added, and when the temperature of molten iron rises to 1400-1410 DEG C, the remaining 1/11 mass part of carburant is added in a mirror surface mode after slagging-off impurity removal; and sampling analysis, blending, tapping, nodulizing and inoculation treatment are performed until pouring is completed. According to the process, the scrap steel is used as a main raw material, and the joint carbon adding mode of middle adding and mirror surface adding is adopted for preparing high-silicon-molybdenum ductile cast iron with high strength and high impact toughness.

Point-by-point excitation well depth designing method based on uniform near-surface model

The invention discloses a point-by-point excitation well depth designing method based on a uniform near-surface model. The method comprises the following steps of: A. obtaining optimum lithological hierarchical data and optimum speed hierarchical data by combining interpretation; B. programming a data conversion interface program and loading multiple attribute data; C. establishing a comprehensive and uniform near-surface model according to the lithological hierarchical data and the optimum speed hierarchical data obtained after combining interpretation, data of the submersible surface and submersible well, speed data and absorption attenuation A values; D. carrying out point-by-point excitation well depth designing and static correction value calculation on the uniform near-surface model; and E. loading the generated excitation well depth dispersive point data into the system again to generate a contour map in a CGM (Computer Graphic Metafile)format, marking a position by using a small rectangular patters, displaying the depth value of the point, and plotting the processed result map by using a plotter. The invention can optimize the excitation well depth design, enhance the signal-to-noise ratio of the earthquake collecting single-shot record, and greatly improve the information quality.

Glass tube molding mold, device and method

The invention discloses a glass tube molding mold, device and method. The mold is installed at a discharge port of a molten glass material supply device and comprises an inner mold body, and the inner mold body is installed at the discharge port of the material supply device and comprises a connecting rod and a molding part; the molding part comprises a molding surface, the molding surface is the surface, facing the discharge port, of the molding part and is a spherical surface or conical surface or curved surface which protrudes towards the connecting rod, and at least one material groove is formed in the molding surface in a concaved mode and extends to the bottom of the molding surface from the corresponding joints. In the manufacturing technology, molten glass flows to the molding surface of the inner mold body through flow channel clearances formed in the discharge port, the molding surface guides the molten glass to be diffused in a curved surface mode to form a tube in the initial stage that the molten glass is converted from the flow state to the solidified state, inner ribs are formed by the molten glass flowing along the material grooves on the inner side of the tube, and then the glass tube is driven by a traction device to rotate, so that the inner ribs are in a spiral shape. Accordingly, the production problems in the prior art are solved, and the glass tube with the spiral ribs on the inner wall is produced.

Plug dislocation interlocking apparatus used by general-purpose converter

The invention relates to a plug dislocation interlocking apparatus used by a general-purpose converter. The apparatus comprises a location plate and an interlocking slide block; a plurality of parallel linear grooves are opened on the location plate; folded grooves that are corresponded to the linear grooves are opened on the interlocking slide block; upper end spacings of the folded grooves are the same as spacings of the corresponded linear grooves of the location plate; a lower end spacing of each the folded groove is different from the spacing of the upper end groove of each the folded groove; and a central portion of the two ends of each the folded groove is in a sloped surface mode for transition; besides, handles that are connected with all plugs pass through the folded grooves of the interlocking slide block and can be moved up and down along the linear grooves on the location plate; and simultaneously, the interlocking slide block is driven to make translation movements left and right. According to the apparatus provided in the invention, it is utilized that spacings of the folded grooves and the linear grooves are not equal; therefore, when any type of plug is slipped off, an interlocking slide block is moved and dislocation of grooves and grooves is formed, so that other plugs are blocked by the slide block and can be slit downwardly; and thus the dislocation interlocking function is realized; moreover, a movable pin is utilized to realize position location, thereby improving security and reliability of the general-purpose converter.

Rotating rod type gate hoist

A rotating rod type gate hoist is provided with a motor, a rack, a screw and a gate, wherein the screw is installed on the rack, a transmission mechanism is connected between an output shaft of the motor and the screw, a nut is connected to the gate, the screw is matched with the nut, a shaft sleeve is fixed to the gate, the nut is installed in the shaft sleeve, the outer side face of the nut and the surface of an inner hole of the shaft sleeve are spherical surfaces, and the outer side face of the nut is in interference fit with the inner hole of the shaft sleeve. The screw is sleeved with a multiple-section telescopic sleeve, the upper end of the sleeve is connected with the rack, and the lower end of the sleeve is connected with the gate or the shaft sleeve. Due to the fact that the outer side face of the nut is matched with the inner hole of the shaft sleeve in a spherical surface mode, the nut and the shaft sleeve can relatively deflect for compensation to avoid nut-screw friction increase caused by gate deflection when tiny deflection occurs in the vertical direction during vertical movement of the gate. The arranged sleeve can prevent floating objects on the water surface from being wound around the screw. The rotating rod type gate hoist is reasonable and compact in structure, stable in operation, small in resistance and long in service life.
