Description

Multifunctional molten iron sampling die Technical Field The utility model relates to the technical field of steel detection equipment, in particular to a multifunctional molten iron sampling die. Background In the steelmaking production process, the content of molten iron components is measured by a spectrum analyzer to see whether the content of all elements reaches the standard, and the common operation mode is that the molten iron is sampled by a sampling device, and a sample is taken out after cooling and molding, and then is detected and analyzed by the spectrum analyzer. In the steelmaking process, gas analysis is also required for the molten iron. The two analysis samples are characterized by a thin shank sample, typically a 5-8mm (gas analysis) ingot sample, and a 30-50mm (spectroscopic analysis) diameter. The existing sampling device is usually a sample cup, a containing cavity is arranged in the sample cup, molten iron is poured into the containing cavity and is cooled into a sample block and then poured out, and the sampling device has the following problems that 1, part of bubbles generated in the process of pouring the molten iron into the containing cavity cannot be discharged in time, so that the components and the content of a sample and actual molten steel are different, the spectral analysis result is inaccurate, and 2, the sample is inconvenient to demould. 3. If the thin handle sample and the ingot sample are sampled once, air extrusion is carried out on the thin handle sample at the bottom to cause bubbling and non-molding, and if the thin handle sample is large at the top, the pipe is thin, the flow rate is not fast enough, and the problem of hollowness is caused. Disclosure of utility model The utility model aims to solve the technical problem of providing a multifunctional molten iron sampling die which can finish the collection of spectrum analysis and gas analysis samples at one time and has good demoulding effect and convenient operation. In order to solve the technical problems, the technical scheme includes that the multifunctional molten iron sampling die comprises an L-shaped base and a cuboid-shaped die body arranged on the surface of the L-shaped base, wherein a spectrum analysis sample cavity in the vertical direction and a gas analysis sample cavity in the horizontal direction are arranged in the die body, the gas analysis sample cavity is communicated with the lower part of the spectrum analysis sample cavity, the die body, the spectrum analysis sample cavity and the gas analysis sample cavity in the horizontal direction are divided into two halves by a vertical surface where a symmetry axis of the L-shaped base is located, and magnets are respectively arranged on the two halves of the die body. The multifunctional molten iron sampling die has the beneficial effects that the spectrum and gas analysis sample can be simultaneously obtained through single sampling by means of an innovative split channel design and a magnetic attraction attaching structure. Specifically, utilize the two halves drawing of patterns of mould body, replace traditional drawing of patterns, the drawing of patterns effect is good, and magnetism is inhaled more and is favorable to the mould laminating, makes things convenient for the switch. The design of L type base utilizes the existence of magnetism to inhale slight gap, avoids the exhaust hole, and L type base roughness is guaranteed, can not be because of the bottom unevenness, needs whole change. Saving the use cost. By using the cooling time difference, the gas and the spectrum sample can be cut off rapidly. And performing advection molding by utilizing the self pressure of molten iron. The design of cavity has avoided thin handle sample at the top, and the end is big, and the pipe is thin, can lead to, and the velocity of flow is not fast enough, and causes hollow problem. If at the bottom, air presses, causing bubbling, non-molding.
