Abstract
The utility model relates to an affiliated appliance for smelting steels, which is especially designed in order to solve the problems that the time for sampling and sample preparation of the existing sampler is long, data of testing steel samples are not accurate, and time utilization is longer. The utility model has a structure that a collecting and preparing device is adhered in a sheath, the front port of the collecting and preparing device is provided with a protecting cap, and the back port is sheathed with a cooling cup. The cup bottom of the cooling cup is provided with a through hole, and the sheath is spliced on the front port of a a straight tube of a long handle. When a sampler is used, sampling time is 3-4 seconds, and the diameter of the prepared steel sample is less than 4 mm. The utility model has the advantages of no oxidation and no pollution, accurate data and high analysis precision, a melting test can be directly carried out on a carbon sulfur apparatus, and the time of sampling and test is shortened to two minutes every time.
Description
The utility model relates to a kind of used attached apparatus of smelting of steel, specifically a kind of molten steel sampler.
In the smelting process of steel, change in order in time to grasp the molten steel composition, must often from molten steel, take a sample and analyze.Existing molten steel sampling mode is divided into two kinds substantially: a kind of is traditional big dipper sampling, is commonly called as and draws a design; Another kind is to adopt cake sample sampler, the steel sample shape such as the chess piece of taking-up.During big dipper sampling, because molten steel is exposed in the air fully, thereby oxidation is serious, and the sample preparation time is long, has a strong impact on the analysis precision and the analysis speed of molten steel, and has extended thus the steel-making time, has improved cost and energy consumption.Still needing after the grinder buffing polishing in the steel sample surface that cake sample sampler is taken out, just can chemically examine.Still have problem of oxidation to exist in these operating process, and prolong the sample preparation time, influence sample preparation speed.In addition, the metal cup box of this sampler sampling usefulness has also caused secondary pollution to the steel sample, influences steel sample composition, causes the analysis data distortion, and analysis precision is not high.Therefore, have the use of molten steel sampler now, directly influenced the smelting quality of steel, strengthened energy consumption and cost.
The purpose of this utility model just provides a kind of aciculiform fast thawing molten steel sampler of avoiding secondary pollution, steel sample directly to inspect by ready samples, gets the sample preparation time with shortening, improves analysis precision, finally improves the smelting quality of steel, reduces the cost and the energy consumption of steel-making.
The utility model is achieved in that sampler is to be bonded with by bonding agent to gather and process device in sheath, the front port of gathering and processing device is with helmet, and its rear end muzzle has cooling cup, and the cup tail band of cooling cup has through hole, and sheath is plugged on the front port of long handle straight tube.
The device of gathering and processing in the utility model is to make with high temperature resistant, high-purity, shock proof nonmetallic materials, so that the steel sample is not subjected to such environmental effects.Specifically can be the needle-like quartz glass tube, its middle part is the reaction chamber of spherical protuberances, and the body at reaction chamber rear portion is the steel specimen chamber.
In the use, preset the deoxidizer of solid metal material in gathering and processing the device reaction chamber, hand-held long handle straight tube inserts sampler in the molten steel.Because the protective effect of helmet, make sampler can break through the molten steel top layer smoothly and enter wherein.Because the high temperature of molten steel, helmet is melted rapidly, and molten steel enters to be gathered and processed in the device, enters the steel specimen chamber in reaction chamber with after the deoxidizer reaction deoxidation, and is cooled after running into cooling cup.Through hole at the bottom of the cooling cup cup can make molten steel enter smoothly and gather and process device.At the same time, extract sampler out, the bonding agent of gathering and processing between device and the sheath becomes crisp behind high temperature.Sampler one is knocked on working plate gently, gather and process device and promptly deviate from sheath, and broken, isolate not oxidized, unpolluted aciculiform steel sample.The thin rod end diameter of steel sample can be below 4mm, thereby can directly use the far infrared carbon and sulfur analytical instrument, carries out the Flashmelt chemical examination, draws the analysis data.
Key of the present utility model is, molten steel sampling and sample preparation are carried out simultaneously, unite two into one, and the steel sample can directly inspect by ready samples, exempted the time and the pollution of processing steel sample.Be 3-4 second sample time, and shorten half traditional sample time; Each sample examination time can shorten 2 minutes, and analysis data is accurate, and analysis precision improves.With 15 tons of converters is example, about 20 minutes of every stove steel smelting time, use this sampler sample examination, and can save time 10%, reduce by 10%, one converter of smelting energy consumption and can have more 7 stove steel every day, economic benefit is huge.Because analysis data is accurate, improved smelting quality simultaneously, the tapping yield rate can reach 100%, and makes smelting high-quality steel become possibility.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the sheath 3 of this sampler is the resistant to elevated temperatures porcelain sheath of high-quality, and there is inside and outside reducing at the middle part.What quartz glass was made gathers and processes device 5 shapes as injection needle-like, penetrates in the sheath 3, and the reaction chamber 5a at its middle part is positioned at the thick muzzle pipe of sheath 3.Outside filling magnesia bonding agent forms adhesive phase 8.Gather and process on the front port of device 5 and be with double-deck helmet, outer helmet 1 is bonded in the internal orifice of sheath 3, and internal layer helmet 2 is plugged on sheath 3 and gathers and processes in the adhesive phase 8 between the device 5.The effect that double-deck helmet is set is, after outer helmet 1 is melted when breaking through the molten steel top layer, also has 2 protections of internal layer helmet to walk one section, makes to gather and process device and arrive the inner sampling of molten steel smoothly.If adopt the individual layer helmet then, make the Structural Design Requirement of helmet too harsh, and use limitation to increase because of needs are considered impact strength, fusing time, to walk distance etc. all multifactor.
Gather and process the tubule steel specimen chamber 5b at the reaction chamber 5a rear portion of device 5, pass sheath 3, its end is with cooling cup 7.Cooling cup has central through hole by being adhesively fixed at the bottom of its glass.For preventing to gather and process device 5 swing crushings, be connected to sheath in sheath 3 rear sleeve and the fender bracket 6 of gathering and processing organ pipe body and cooling cup.Sheath 3 is plugged on the front port of long handle straight tube 4.Because this sampler is a disposable utensil, so for reducing cost and avoiding the steel sample to pollute, the board rolls of available coating fire resistive material is made the long handle straight tube.
