The international standard ISO 9185 for molten metal protection in foreign countries 2007 assessment of protective clothing-material molten metal splash resistance has the testing principle that a proper amount of molten metal is sputtered onto a sample placed at a certain angle in the testing process, and a PVC film is attached to the back of the sample to be in contact with the sample. The damage was evaluated by recording the change in the PVC film after the sputtering process and, according to the test results, repeated tests were performed using greater or lesser amounts of metal until the degree of PVC film damage was minimal. The test method has obviously higher sample strength and is suitable for production occasions such as metal smelting and the like.

Fig. 1 is a schematic structural diagram schematically illustrating a molten metal splash test device for a protective suit according to an embodiment of the present invention, where the device may be applied to a test instrument.
As shown in fig. 1, the apparatus mainly includes a controller, a crucible advancing unit 10, a melting and heating unit 20, and a pouring unit 30.
In practical applications, the controller is electrically connected to the crucible advancing unit 10, the melting and heating unit 20 and the pouring unit 30, respectively, and is configured to control the crucible advancing unit 10 to move the crucible 10, control the melting and heating unit 20 to heat the molten material in the crucible 10, and control the pouring unit 30 to pour the molten material in the crucible 10.
Specifically, the controller controls the crucible 10 to move and block liquid, the moving unit controls the placing position of the crucible 10, and through the control of the placing position of the crucible 10, on one hand, the crucible 10 can be arranged in the high-frequency furnace heating copper pipe 8 to heat the molten substance in the crucible 10, and on the other hand, the crucible 10 can be arranged on the crucible support 11 to pour the molten substance in the crucible 10.
Further, the controller controls the high-frequency power in the melting and heating unit 20 by the collected melting temperature, and controls the heating temperature of the molten material in the crucible 10 by adjusting the heating temperature of the high-frequency furnace for heating the copper tube 8. Wherein, the melting temperature is acquired by a melting temperature sensor 9 arranged in the melting and heating unit 20, and the melting temperature sensor 9 is electrically connected with the controller.
Further, the controller adjusts the position between the sample holder 18 and the crucible holder 11 by controlling the rotation of the height motor 16 and the rotation of the angle motor 17 below the sample holder 18, and when the sample holder 18 is disposed below the crucible holder 11, the controller causes the crucible 10 disposed on the crucible holder 11 to pour the molten material in the crucible 10 onto the sample holder 18 by controlling the rotation speed of the rotation motor 13 disposed on the crucible holder 11, thereby achieving pouring of the sample holder 18.

Specifically, the data acquisition unit is electrically connected with the controller through an RS485 communication protocol, so that the automatic control of the device is realized.
According to the crucible forward-moving unit 10 in the protective clothing molten metal splashing test device provided by the embodiment of the invention, the crucible 10 is automatically controlled to move between the heating copper pipe 8 of the high-frequency furnace and the crucible support 11, and the problem that the crucible 10 is moved by manually holding the crucible 10 and a holding tool is solved; the melting heating unit 20 realizes the automatic control of the heating process of different melting substances in the crucible 10 and solves the problem of controlling the heating furnace by manual temperature measurement; the pouring unit 30 realizes automatic detection of pouring temperatures of different molten substances, and simultaneously automatically adjusts the rotating speed and angle of a pouring motor and the angle and height of the sample support 18 according to different molten substances, thereby solving the problems of manual temperature measurement and parameter adjustment.
Fig. 2 is a schematic structural view of a crucible advancing unit 10 according to an embodiment of the present invention, fig. 3 is a schematic structural view of a melting and heating unit 20 according to an embodiment of the present invention, and fig. 4 is a schematic structural view of a pouring unit 30 according to an embodiment of the present invention; the molten metal splash test device for the protective suit is described in detail below with reference to fig. 2 to 4.
As shown in fig. 2, the crucible forward-moving unit 10 mainly includes a guide rail lifting cylinder base 1, a guide rail lifting cylinder 2, a guide rail lifting cylinder limit table 3, a two-position cylinder 4, a finger cylinder base 6 and a finger cylinder 5. Specifically, a guide rail lifting cylinder 2 is fixed on a guide rail lifting cylinder base 1, a guide rail lifting cylinder limiting table 3 is fixed on a center shaft of the guide rail lifting cylinder 2, a double-position cylinder 4 is fixed on the guide rail lifting cylinder limiting table 3, a finger cylinder base 6 is fixed on the center shaft of the double-position cylinder 4, and a finger cylinder 5 is fixed on the finger cylinder base 6.
In the embodiment of the invention, when the controller determines the target placement position of the crucible 10 according to the operation software, the guide rail lifting cylinder 2 is controlled to execute the ascending command or the descending command, because the guide rail lifting cylinder limiting table 3 is fixed on the central shaft of the guide rail lifting cylinder 2, the double-position cylinder 4 is fixed on the guide rail lifting cylinder limiting table 3, correspondingly, when the guide rail lifting cylinder 2 ascends or descends, both the guide rail lifting cylinder limiting table 3 and the double-position cylinder 4 arranged on the guide rail lifting cylinder 2 and the guide rail lifting cylinder 2 ascend or descend simultaneously; further, because the finger cylinder base 6 is fixed on the middle shaft of the two-position cylinder 4, and the finger cylinder 5 is fixed on the finger cylinder base 6, the finger cylinder base 6 and the finger cylinder 5 can also ascend or descend simultaneously with the guide rail lifting cylinder 2.
Because the controller already determines the target placing position of the crucible 10, the double-position cylinder 4 is controlled to be positioned on the target placing position of the crucible 10, for example, when the target placing position of the crucible 10 is the position of the high-frequency furnace heating copper pipe 8, the target position positioned by the double-position cylinder 4 is above the high-frequency furnace heating copper pipe 8; when the target placement position of the crucible 10 is on the crucible support 11 of the pouring unit 30, then the target position where the two-position cylinder 4 is positioned is above the crucible support 11. In the embodiment of the invention, the finger cylinder 5 is used for clamping or placing the crucible 10, for example, when the target position positioned by the double-position cylinder 4 is above the heating copper pipe 8 of the high-frequency furnace, the finger cylinder 5 is used for clamping the crucible 10; and when the target position where the two-position cylinder 4 is positioned is above the crucible support 11, the finger cylinder 5 places the crucible 10. After the finger cylinder 5 finishes moving the crucible 10, the crucible forward moving unit 10 returns to the initial state, thereby indicating that the position adjustment of the crucible 10 is finished in the current state.
It should be noted that the holding or placing process by the finger cylinder 5 is performed only for the crucible 10 that has been heated. For example, if the crucible 10 is not heated yet, when the target position to which the two-position cylinder 4 is positioned is above the copper tube 8 heated in the induction furnace, the finger cylinder 5 places the crucible 10 so that the crucible 10 is heated in the copper tube 8 heated in the induction furnace. In other words, when the crucible 10 is completely poured, the finger cylinder 5 holds the crucible 10 while the target position where the two-position cylinder 4 is positioned is above the crucible support 11. In the embodiment of the present invention, the holding action or the placing action performed by the finger cylinder 5 on the crucible holder 11 and in the high-frequency furnace heating copper pipe 8 is not particularly limited.
As shown in fig. 3, the melting and heating unit 20 includes a high-frequency furnace 20, a high-frequency furnace heating copper pipe base 7, a high-frequency furnace heating copper pipe 8, and a melting temperature sensor 9. Specifically, the high-frequency furnace heating copper pipe 8 is arranged on the high-frequency furnace heating copper pipe base 7, one end of the high-frequency furnace heating copper pipe 8 is electrically connected with the high-frequency furnace 20, the high-frequency furnace 20 is arranged below the high-frequency furnace heating copper pipe base 7, and the melting temperature sensor 9 is arranged above the high-frequency furnace heating copper pipe 8 and used for detecting the melting temperature of the molten substance in the crucible 10.
In the embodiment of the invention, when the controller receives the melting temperature sent by the melting temperature sensor 9, the working power of the high-frequency furnace 20 is controlled according to the melting temperature, and one end of the high-frequency furnace 20 is electrically connected with the high-frequency furnace heating copper pipe 8, so that the high-frequency furnace heating copper pipe 8 can heat the crucible 10 arranged in the high-frequency furnace heating copper pipe 8, and then the molten substance arranged in the crucible 10 can be heated.
It should be noted that the controller needs to control the operating power of the high-frequency furnace 20 according to the melting temperature, and when the melting temperature reaches the target melting temperature, the controller may turn off the high-frequency furnace 20; and when the melting temperature does not reach the target melting temperature, the controller may control the high-frequency furnace 20 to continue heating. The target melting temperature here is determined based on the molten material placed in the crucible 10.
As shown in fig. 4, the pouring unit 30 includes a crucible holder 11, a rotation motor 13, a pouring holder 15, a height motor 16, an angle motor 17, a sample holder 18, a sand table 19, and a pouring temperature sensor 12.

In the embodiment of the invention, when the controller receives technical parameters of the casting substance, the rotating speed and the rotating angle of the rotating motor 13 arranged on the crucible support 11 can be adjusted, the horizontal height of the sample support 18 is adjusted through the height motor 16, and the horizontal angle of the sample support 18 is adjusted through the angle motor 17; further, after the controller receives that the pouring temperature sent by the pouring temperature sensor 12 reaches the target pouring temperature, the controller controls the rotating motor 13 to start rotating, and after the rotating motor 13 rotates to a specified angle, the rotating motor 13 starts to rotate reversely, and at the same time, the molten material in the crucible 10 is poured onto the sample support 18, it should be noted that, in practical application, a fabric sample is arranged on the sample support 18, and the fabric sample arranged on the sample support 18 is completely poured by the molten material in the crucible 10. Further, in order to prevent the material under the sample holder 18 from being damaged by the high temperature of the molten material in the crucible 10, the excessive molten material is collected by a sand table 19 provided under the sample holder 18.
In practical applications, the controller controls the rotation motor 13, the height motor 16 and the angle motor 17 before or after receiving the casting temperature.
