Abstract: In the testing process of all steel radial load tires, the X-ray detection machine, as the core
equipment, directly determines the level of product quality control in terms of detection accuracy and
operational stability. As the core component of an X-ray inspection machine, the X-ray tube inevitably
generates a large amount of heat energy due to its energy conversion characteristics during operation,
making the efficiency of its cooling system a key factor restricting equipment performance. This article
focuses on the detection scenario of the skeleton structure of radial tires, and systematically analyzes the
heating mechanism of X-ray tubes, the technical bottlenecks of existing cooling systems, and the attenuation
mechanism of cooling system efficiency through a combination of thermodynamic simulation and
experimental verification. A kind of compound optimization scheme of adding compressor and cooler was
put forward. Through the verification of actual working conditions, distilled water (conductivity ≤ 2 μS/cm)
and contact microchannel heat exchanger (contact area increased by 87%) were introduced to stabilize
the working temperature of X-ray tube within the design range of (45 ± 3) ℃ . After 240 hours of continuous
working condition testing, the thermal load carrying capacity of the equipment has been increased by 25%,
and the expected service life of the pipe head has been extended to 3 500 working hours, thereby improving
the economic operation efficiency of the equipment.

两厂关停！炭黑巨头确认损失 12.4 亿元
Two factories shut down! carbon black giant confirms loss of 1.24 billion yuan

国际中橡投资控股股份有限公司 ( 以下简称 “ 国际中橡 ”) 在近日召开的股东大会上，报告了中国未来的发展
策略。
会上，国际中橡董事长辜公怡透露，面对中国市场长年亏损，重庆厂出售已于去年底敲定，鞍山厂也在今年
初关闭，2024 年确认一次性损失 12.4 亿元，随着多年亏损厂区的正式结束，国际中橡未来将转向具成长潜力的
地区重振旗鼓。
据了解，国际中橡在战略调整的同时，也积极布局未来增长点。
总经理李超儒在会上详细阐述了公司在中国市场的未来规划。他表示，公司将以马鞍山厂为核心，实施 “ 全
产全销 ” 策略，并计划在下半年引入蒸气销售业务，以进一步优化营收结构，提升盈利能力。
此外，李超儒还透露，马鞍山厂已被选定为 SCB( 可持续炭黑 ) 技术的试点基地，公司正致力于提升以
TPO( 热裂解油 ) 为原料的生产能力。目前，该厂已完成 25% TPO 混合比例的试产与成品测试，预计年底前将实
现 100% TPO 生产可持续炭黑，届时将成为全球第三家掌握此项技术的企业，与 Orion、Cabot 等国际巨头并驾
齐驱。
另外，李超儒指出，台湾林园厂已于 2024 年完成检修与锅炉更新，同时掌握碳纳米管研发的技术突破，现
积极规划相关产品的投产。李超儒总经理预测，国际中橡 2025 预估全年可销售导电炭黑 5 500 t，几乎多出 2023
销量的一倍，有望创下历史新高。
