<p>The invention relates to a system for simultaneous collection of liquid steel sample including acquisition of temperature data from an LD Converter during steel making process. The system comprise a dual acting probe device with a meltable protective cap enabled to collect liquid steel sample from the LD converter and simultaneously acquire temperature data inside the converter for transmission of the acquired data via a triangle piece connector for display in a displaying unit. The system also includes a common single Lance adaptable to the probe device, allowing dipping of the system inside the LD converter at different angles including withdrawal of the system from the converter subsequent to collection of sample and transmission of temperature data. The system is characterized in that the dual acting probe device comprises a thermocouple including a copper wire, and being connected to a bath temperature indicator for acquiring and transmitting temperature data; a splitted metal mould enabled to produce a cavity when closed at a first end to allow ingress of molten steel via a silica tube upon insertion of the system into the converter, the second end of the mold attached to said silica tube; a guide bush to connect the probe device with the common single lance; and a sand shell accommodating the thermocouple, metal mould, silica tube, and the triangle piece connector, the shell allowing the hot molten metal to cool down quickly when the metal introduced into the mold.</p> |
